The camera port of the microscope is roughly divided into the following two types: JIS lens and C mount
(Besides that, there are other classic or foreign types)
|
JIS lens (straight lens diameter of 23.2mm) |
C-mount (Screw M25.4mm) |
 |
 |
If you want to connect a camera with a “C-mount” to the mount of a microscope, there are two methods:
Convert the camera port on the microscope side to C-mount:
If the microscope already has a C-mount, you can directly attach the camera to it.
However, if the microscope has a JIS (Japanese Industrial Standard) microscope tube, you will need to modify the port on the microscope side.
Please note that not all microscopes allow for port conversion, so it may not be possible in some cases.
The biggest advantage of this camera is to be connected to the eyepiece section.
<Camera for microscope attached to C mount>
C mount is one of mount camera standards. (Please refer to “C mount, CS mount”)
Because of mount camera standards, a microscope camera is unnecessary.
It is the greatest merit that C mount type general purpose camera can be connected as it is. (Can not be connected to eyepiece section.)
However, the field of view (magnification) will change depending on the size of the image sensor on the camera.
As there is no lens on the camera, the magnification can not be adjusted.
(It must be selected when purchasing the camera adapter for microscope)
The following picture is a system diagram of some microscope manufacturers.
C-mount has various types from 0.25X to 0.63X.
It is necessary to purchase C mount matches to the number of inches of C mount camera.
Since it’s all C mount, the focus themselves matches. However, the field of view will be narrow or vignetting (shadows of four corners of the image) occurs.
2. Make a C-mount camera compatible with a JIS (Japanese Industrial Standard) microscope tube
 |
|
When you attach a JIS microscope tube adapter lens to your camera, you can mount it onto the JIS microscope tube. |
 |
|
The biggest advantage of this camera is that it can also be connected to the eyepiece lens section. |
 |
| If you remove the front lens, you can also connect it to a C-mount. Please refer to the instructions on “How to Connect a Microscope Camera to a C-mount” for reference. |
3. Field of View Considerations:
Camera internal sensors (CMOS or CCD) come in various sizes. Ideally, the lens magnification should be adjusted according to the sensor’s size.
If the sensor size is 1/2 inch, it is recommended to choose a lens with approximately 0.5x magnification.
