What is an auxiliary lens (front converter lens)?

You can change the magnification by attaching it to the front (object side) of the main lens. It is also possible to change WD (working distance).

You can see that the field of view has expanded by attaching 0.5 times the auxiliary lens.

* When using a 0.5 times auxiliary lens, the working distance changes and the distance from the lighting to the object increases. Thus, it is necessary to change the position of the lighting using the LED angle.

How to choose CCTV lens?

From the size of the object you want to shoot, you can calculate the necessary lenses.

The needed thing at this time is the size of the image pickup device of the camera and the distance to the object (WD).

CCTV

 

For example, if you want to secure a vertical field of view of 300 mm with 1 m WD, how many millimeters should the f value be? (I will use a 1/2 inch camera.)

 

The image sensor size of 1/2 inch camera as follows.

撮像素子サイズ

f = (distance to object (mm) X vertical size of imaging device (mm) / vertical field of view

= (1000 mm X 4.8 mm) / 300 mm = 16 mm

Choosing a lens with f = 16 mm will ensure the desired vertical field of view.

You can calculate the horizontal field of view as well.

 

By the way, you can easily calculate the horizontal field of view.

If it is a square type imaging device, the aspect ratio is 4: 3 . Therefore, the horizontal field of view will be 400 mm without calculation.

CCTVレンズ
 

We have various CCTV lenses available. Please check this for details.

 

What is macro lens / macro zoom lens?

A lens designed for photographing a close distance is called a macro lens.

In the macro lens, the magnification can be changed continuously, and the focal length is constant (unchanged) is called macro zoom lens.

マクロズームレンズ マクロズームレンズ

Though the magnification can be changed continuously, the one whose focal length changes will not be strictly a zoom lens.

Sometimes it is called a variable magnification lens distinguished from a zoom lens.

可変倍率レンズ 可変倍率レンズ

 

If you do not change the magnification frequently and want to reduce the price, you should you variable magnification lens. If you change the magnification frequently, a macro zoom lens is recommended.

What’s zoom lens?

Zoom lens is a lens in which the image size can be varied continuously while the image remains in focus.

The zoom ratio of 12 (1:!2) is the physical limit of zoom macro lens.

In addition, the lens in which the magnification can be varied continuously while the image does not remains in focus is not a zoom lens but a lens with variable magnification.
In other words, focal distance changes but magnification also changes is cheaper than the zoom lens is the characteristics of the lens with variable magnification.
Our company has various types of lenses. Please see the products here.

You can choose the lens according to the characteristics such as magnification, focal length, price, etc.

Besides, please consult us to select appropriate lenses. Please contact the technical support.

About explosion-proof specification of borescope

 

The explosion-proof specification will be “Specifications that have taken special technical measures so that it will not be an ignition source of combustibles”.

 

Unlike an endoscope with a built-in camera at the tip, the borescope is made up only lens and fiber. There is no electric thing at all.

(The borescope itself is not an ignition source.)

 

Of course, dedicated equipment is required for light source devices and cameras in environments where explosion-proof is required.

For example, it seems that the following explosion-proof C-mount camera are on sale.

Heat resistant of borescope

Heat resistant of borescope

If it exceeds 150 ° C, a cooling device is required and it becomes a complete custom product.

In case the cooling system is unnecessary, it is up to 150 ° C.

Additional devices are unnecessary so it can be introduced easily.

耐熱ボアスコープ

A separate cooling device is required. It is possible to correspond up to about 1800 ° C.

However, additional equipment such as cooling equipment is also required, so it will be completely customized.

耐熱ボアスコープ

This is only a guide, it shows the following two points.

・The cooling enclosure is mounted in a borescope of φ5.5 or φ4 mm and it is about φ14 mm.

・The maximum length is 1000 mm at 800 ° C. We will designate it as below:

 

耐熱ボアスコープ  

Where to place the water inlet and drain outlet also depends on the customer’s request.

 

   It may be the camera type or direct observation. It will be the specification of the customer’s preference.

     
耐熱ボアスコープ

 

Reference: Custom-made · Heat-resistant scope price

(Price is determined by various conditions, please see it as a guide only)

耐熱ボアスコープ

Optional:

Lighting is attached to normal borescope but in custom case, lighting is optional.

In bad environment, you can also install an air purge so that the tip does not get dirty

I can do it. (We call it as an air cleaner.)

Questions about heat resistant borescope are received from here.

Please fill out the specification sheet below and send it to us by e-mail or fax.

E-mail:info@shodensha.com.vn

※Because all heat-resistant of borescope is made to order, we are sorry that there is no preparation of demonstration machine.

Types and characteristics of endoscope

There are three types of endoscopes, largely divided into three types.

Each has advantages and disadvantages.

You can connect to a PC or view the video on a monitor in any type.

(The required options are different.)

1.Borescope (rigid mirror)

It is a type that contains a rod lens at the tip.

Basically there seem to be many like the following form.

ロッドレンズ

There are also types that can be directly connected to the monitor as shown below.
硬性鏡

(advantage)

Since the tip is only the lens, it can be made small diameter.

It is possible up to φ0.7 mm.

The picture is the most clear when you see only the part of bore.

(disadvantage)
The part of the bore is expensive.
Since the tip is a lens, it is vulnerable to impact.
Since it is a lens, it can not bend the tip.
(you can choose direct view, strabismus, side view as type.)
it can not be made a physically long one. (Generally up to about 30 cm)

2.Fiberscope
The tip is an optical fiber.

ファイバースコープ

(advantage)

The relay section flexes flexibly. (At the level where the fiber will not break)

Can be made thinner than borescope.

It is possible up to φ0.35 mm.

(disadvantage)

The resolution is decided by the number of fibers being bundled.

(As the diameter becomes smaller, the number of bundles decreases and the resolution drops.)

A thin line will be visible at the boundary of each fiber.

Although it is possible to have a length longer than the bore, it attenuates as the light passes through the fiber, so if you lengthen it, a strong light source is required.

3.Advanced Camera Type
A small camera is enclosed at the end of the endoscope.

内視鏡

(Advantages)

Because there is no special lens or fiber, the price is the cheapest.

(There are also expensive ones with various features, but basically it will be cheaper.)

Since the relay section is an electric wire, it can be bent over the fiber.

Since it is electronic equipment, it is a monolithic one with many monitors, so you can make various applied products.

 

(Disadvanatges)

The resolution is determined by the camera.

(The smaller the size, the worse the resolution will be.)

Can not be thinner than the size of the camera. (At the smallest about φ1.8 mm)

 

The advanced camera type has various types as it is not subject to the restrictions of rod lens and fiber.

What’s causes of haze of borescope field / attention on using borescope?

The borescope contains a very elongated “glass” lens (rod lens) inside.

Therefore, if you receive a strong impact instantaneously, the glass lens inside may crack or break.

 

For glass protection, it is enclosed in a stainless steel tube. But, please be careful especially when handling long and small diameter.

How to hang video camera?

  Originally, I used a tripod screw for fixing this camera,
     
     (top of camera)
 

Some people are using four screws by removing the pan head as being uneasy with one point stop.

The same is true for an elderly.

In this case, please make sure that the entry part of the screw from the case of the camera is 3 ~ 4 mm.

(It will hit the connector when it is long.)

There is another method in case of hanging down.

 

  You can use it as
shown on the left picture.

 

What’s the most suitable camera for borescope?

Borescope is a product that often observes the inside of metal workpieces.

Depending on the metal processing state, R, irregularities, the difference in brightness may increase.

In that case, using a wide range (wide dynamic range) camera may make it easier to see.

 

We compared the high-sensitivity wide-range Full HD camera (BA200HD)adopted for our boothcope with our general-purpose video camera (GR-i700).

 

Video Camera the high-sensitivity
wide-range Full HD camera

●Observation of a part of a small engine (structure with a threaded portion at the back of the cylinder)

●Observe the straight tube part and thread part with a direct viewing type borescope

Video Camera the high-sensitivity
wide-range Full HD camera

 

If there are R and unevenness in the metal part, the halation part and black part will be more.

When using a wide range camera, the range that can be observed spreads.

As shown in the figure above, the scope of observation of the screw portion at the back which has been difficult to observe with the conventional video camera has expanded.

Extension of video cable

There is no clear provision on the video cable like a USB cable.

 

If it is only the part of the video signal, I think that about 10 m is safe if it is an ordinary pincode (RCA terminal) as achievement.

If it is a coaxial cable (BNC terminal), it can transmit without feeling deterioration of about 100 to 200 m.

 

If you really want to use the RCA terminal, the terminals are sold as RCA terminal, the cable as coaxial cable, etc.

同軸ケーブル

External device that stores video signals

Video signals are general purpose video signals.

One of the advantages of using a video signal is that a wealth of external equipment can be obtained at a low price.

This time we will introduce some recorder.

(1) Conversion cable

It is a conversion cable introduced in “How to convert video signal to USB“.

Because it saves with software on PC side, still images and movies can be saved depending on software.

変換ケーブル

(2)Battery-driven recorder

It changed a bit, it is a battery-driven recorder.

It is made overseas but you can purchase it with Amazon etc.

You can save not only videos but still images.

The recording medium is this body. The record data is sucked up by PC with USB.

Since there is no output terminal, it can not output to the monitor.

電池駆動の記録器

(3)USB memory compatible video recorder with division function

The video signal recorder sold at our company can save both movies and still images.

It is a video recorder GRAV-1 with a division function compatible with USB memory.

The recording medium is a USB memory. You can save movies and still images.

It is also possible to save using an external trigger.

(It will be only still images. * It can be saved only for movie saving by special order correspondence.)

USBメモリ対応分割機能付ビデオレコーダー USBメモリ対応分割機能付ビデオレコーダー
   

 

For video signals, video recording machines are mainstream.

When saving of still images is unnecessary, the number of options increases and the price becomes low price.

(4) Compact DVR

 Small DVR only for saving movies is sold at the site of burglar alarm equipment.

小型DVR

(5)Hard disk recorder

Many low-priced hard disk recorders are also on sale.

Long time recording is also suitable for video cameras.

We will introduce one hard disk recorder that can record for 2 months with monitor with long time recording.

ハードディスクレコーダー

(6)Skip back recorder

There is also a skip back recorder.

It records the image before and after the trigger is entered with a sensor etc.

スキップバックレコーダー

How to transmit video signal to USB?

The video signal is an extremely versatile video system.

Various external devices are also on sale.

Various items to convert to USB are also on sale.

Power supply is unnecessary, and it seems that many are small and inexpensive.

The bottom photo is about 4000 yen, but there seems to be some sold at around 2000 yen.

ビデオ信号外部機器

In the case of video signal (NTSC), the total number of scanning lines is 525 lines.

When converting to USB, it becomes about 640 X 480 (about 300 thousand pixels equivalent).

Recent USB cameras are commonly megapixels. Compared to them, the resolution is slightly inferior.

However, the frame rate is fast and the data capacity is small, it is suitable for storing moving images.

Distribution of video signal

Video signals may be distributed and used. (Using monitor and recorder)

When distributing the video signal, it can also be split into two using connectors and cables.

Many products are also sold.

ケーブル コネクタ
   

In this case the image deteriorates.

If you use a video distributor, you can basically distribute video signals losslessly.

●Split at connector → Degraded video ● Split at splitter → Basically undamaged
コネクタで分割→映像劣化 分割器で分割→基本的には無損出
   

<Wiring example>

The divider divides the video signal into two and outputs it to the video recorder and monitor

You can take in that movie to PC and operate fast forwarding etc using software separately.

You can also change playback speed, fast forward, rewind, playback speed in Windows Media Player and with GOM PLAYER (free software). You can also play, fast forward, rewind and change the playback speed as well as frame advance too.

Please contact technical support for details.

Do you have any software that can play / fast forward / rewind / frame forward / slow play an saved AVI file using video microscope?

The number of video recorder GRAV-1

Our video recorder GRAV – 1 saves images in USB memory.

Supported USB memory is up to 32GB with FAT32 format.
Both jpeg and bitmap can be saved. If it is jpeg of compression system, the file capacity will be about 100 KB / sheet.

In terms of calculation, 320.000 sheets can be saved.

However, FAT32 has a limit on the number of files and about 65000 files are the limit in the root directory.
In other words, even if there is a capacity margin, it will be the upper limit of saving 65000 sheets.

ビデオレコーダー GRAV-1

 

GR-AV1 automatically creates three folders in the same directory and saves the data continuously in this folder.

Since you can not change the directory, it is affected by the limitation on the number of files above.

How to record in 24h?

It is impossible except for video microscope if long time recording is more than 24 hours
It is possible to record images taken with the video microscope on the hard disk for more than 24 hours of recording.

For example, if it is a method to record on this 2 TB (terabyte) hard disk, it will be possible to record even more than 10 days.

ハードディスク

Ports are attached to hard disk can be handled with BNC port.

ハードディスクに取り付ける端子はBNC端子でも対応可能

 

Although it is possible to convert the video terminal to USB and save it on the PC, it becomes 1 MB or more by simply recording 1 second with VGA (640 x 480). Therefore, the method of converting to USB and saving on the PC is not very realistic.

Please feel free to contact technical support for Hard Disk.

Moreover, it is the optimum microscope when you want to save the movie, shooting is possible even 24 hours if connected to the HD recorder.

The disadvantage is that the resolution is low. (A full high-vision microscope with high resolution is also available.) Another hardware (such as a video recorder compatible with SD card) is required to save images. (However, the video signal is a general signal, it is advantageous to have abundant external equipment.) It is also possible to use USB video capture to display on a PC via a USB cable but the image becomes rough in some cases.

How to check photographed images of HD camera in real time?

Our high definition camera and PC monitor direct camera have a USB port. Normally, you can insert a USB memory here.
Pictures taken are saved in this USB memory.
In order to see the saved image, you need to unplug the USB memory and connect it to the PC.

I will show you how to send the saving images directly to the PC or tablet by omitting the movement of the USB memory.

That is WiFi internal SD card, wireless SD card.

FlashAir

 

Connect this to USB port of camera using USB-SD converter

USB-SD変換器を使ってカメラのUSBポートに接続 USB-SD変換器を使ってカメラのUSBポートに接続

 

The setting method differs slightly depending on the manufacturer of the card. But the following two steps are very necessary.

1. Download the application from the manufacturer’s website
2. Recognize SD card with Wifi compatible PC with Wifi connection

After setting, you can do something like the picture below.
The above monitor is a Live image directly connected to the camera.
The picture taken on the bottom monitor (tablet) will be saved

上のモニタはカメラと直結したLive映像

After disconnecting the shutter of the camera, it is necessary to update the PC or tablet side. But if you press “F5” which was a function key and reload it, you can immediately check the latest recording video. WiFi built-in SD card for cloud is also available.

If you use this, images will be stored on the cloud. Various types of wireless SD cards are on sale. However, when using them with our camera, please note that it is not guaranteed to operate with all cards. Our company is using Toshiba’s flash air right now.

We also checked the operation of the old type of Eye-Fi and confirmed that there is no problem. However, Eye-Fi’s new type (compatible with the cloud) did not work properly with our camera.

※ Although image saving was possible, you cannot save images suddenly. There are two common causes.

① When the application of the WifiSD card being used is automatically renewed, Wifi settings may be missing, you will be able to recognize and reserve images by setting again.

② Since SD card reader no longer recognizes SD card readers, there are many times that SD card readers will not recognize when SD cards are slightly misaligned.

Our camera can display on the menu whether the image storage medium is normal or abnormal. If there is no camera mark in the menu of the following photographs, we recognize if camera cannot recognized is attached.

If you do not recognize, you can correspond such as intert/remove SD card or change card reader.

How to record for a long time by HD camera?

High-definition cameras operating independently face limitations in recording video duration. To capture extended video footage spanning several hours, there exist primarily two methodologies: the utilization of a personal computer (“PC”) and an approach abstaining from PC involvement.

 

By employing a PC, one gains the capability to directly record videos onto the storage system of the personal computer, thereby facilitating prolonged recording durations.

 

For a comprehensive understanding of the methodologies involving PC utilization, please refer to the subsequent page.

HDMIレコーダー HR-MINI

The substitution of a high-capacity external HDD (up to 1TB) in lieu of a USB memory enables the potential for protracted recording periods.

As a noteworthy consideration, externally powered HDDs are imperative, as those reliant on bus power will not function. It is essential to employ self-powered HDDs, ensuring an independent power supply for the external HDD.

Furthermore, if the formatting adheres to FAT32, there exists a file size limitation of 4GB. Therefore, for individuals aspiring to record lengthy videos within a single file, employing an HDD formatted with NTFS is recommended.

 

It is crucial to note that operation is not supported with exFAT formatting.

PC is unnecessary. You can save still images and movies. Since it is stored on the SD card, you need to move the SD card to the PC and read it.
Since it has an external trigger terminal, it can be controlled with a foot switch or PLC.

I tried connecting with our full high definition camera.

How to connect camera HD with PC?

There are several ways to input signals from a high definition camera to a PC.

One way is to use a capture board.
However, the shape changes on a notebook PC or a desktop PC, and the shape of the throttle must also be considered.

The advantage lies in the elimination of the process involving the removal of USB memory or SD cards from the camera and their subsequent insertion into the PC. However, it is important to note that, due to the specification of utilizing USB, real-time performance may slightly diminish compared to a direct connection to the monitor.

Additionally, it is imperative for the PC to be equipped with a USB 3.0 port, as the device will not operate with a USB 2.0 port. Furthermore, compatibility with high-definition cameras is extended to include the utilization of standard measurement software for microscopes.

What’s High Vision?

Hi-Vision is a high-definition video standard. There are several kinds among them. (It is expressed by effective vertical resolution and scanning method.)

Those with a vertical resolution of 1080 are called “Full Hi-Vision (Full HD)”. Something less than this may be referred to as “secondary high vision”.

(I usually think that it is often expressed as “Hi-Vision”.)

There are two kinds of scanning methods as follows.

 

Interlaced scanning method (interlaced scanning method) and progressive scanning method (progressive scanning method).

For interlaced scanning method, add “i” at the end, “p” at the end in the case of the progressive scanning method.

 

If it is 1080p, it becomes full high vision (1920 × 1080) of the progressive scanning method.

If it is 720p, it becomes the sub Hi-Vision (1280 x 720) of the progressive scanning method

Heat resistance of USB camera

The environmental resistance of a normal C mount camera is

・Temperature 0 ° C to 40 ° C
・Humidity 35% to 85% (non condensing)

There seems to be a lot of things. A separate cooling system is necessary to ensure a certain level of heat resistance.

There seems to be some simple things like the following as long as it is at the 60 ° C to 100 ° C level.
(Beyond this, it will be almost custom made.)

Some notes when using multiple high resolution camera with automatic visual enspection software

I think Core i 7 is necessary because it will be quite heavy processing.

Of course, using USB 3.0 is a prerequisite.

As the number of cameras increases, the following problems occur.

・Setting difficult ·

・Cameras that do not recognize due to insufficient bandwidth come out. (I do not know without actually trying this.)

It may be better to increase the number of pixels of the camera and reduce the number. Those with 10 million pixels more than 4 million pixels are more safe.

Currently, I think that there are many PCs with only one USB 3.0 port.

In that case please try using the board which adds USB 3.0 like the picture below. Unlike other general expansion boards, this board is equipped with USB controller chips for the number of ports (only one is common, it is increased to 4 ports like a USB hub) ).

Some notes when using multiple camera on 1 PC

When using multiple USB cameras simultaneously on a single computer, there are three points to consider:

  1. Choice of cameras
  2. Camera limit
  3. CPU capacity

Please note that at the end of the explanation, I will introduce USB cameras that allow you to use multiple cameras simultaneously on a single computer. Please continue reading for more information. 

 

■ It is possible to use multiple cameras with one PC. However, depending on the camera, it may not be possible to use the same model.

(In the case of the same model, the driver software will be the same and may interfere.)

 

< The upper limit of camera quantity>

 

Let’s first consider the bandwidth.
If we are operating a single 3-megapixel camera at 10 frames per second, the data rate would be 30 megabytes per second (3 megapixels × 10 fps = 30 MB/s).
(Each pixel calculated as one byte)

 

<In the case of a USB 2.0 camera> 

The bandwidth of USB 2.0 is 480 Mbps, but the maximum achievable speed in bulk transfer mode is specified to be approximately 52 MB/s. Therefore, simultaneous usage of two or more cameras is not possible (30 MB/s × 2 > 52 MB/s)

 

<In the case of a USB 3.0 camera>

The bandwidth of USB 3.0 is 5 Gbps. However, according to specifications, 8-bit data is converted into a 10-bit signal and transmitted. Therefore, the actual data transfer speed is theoretically limited to 4 Gbps, which is equivalent to 500 MB/s. As a result, it is possible to use a maximum of 16 cameras simultaneously, calculated as 500 MB/s divided by 30 MB/s. (This is strictly considering bandwidth, but in reality, the presence of control data communication and other factors may limit the number of cameras to less than 16.)

If you plan to use multiple cameras, it is advisable to utilize USB 3.0 for optimal performance.

 

<CPU performance >

 

Processing multiple camera images simultaneously is expected to impose a substantial burden on the CPU. While the actual impact may vary depending on the software used, there is no alternative but to test it in practice. In essence, it is advisable to employ a CPU with high processing capabilities.
