If the wide range is 1 to 1000 times, it means that a lens with a zoom ratio of 1: 1000 is necessary. Currently, only the high zoom level of 1: 12 is available around the world.
To achieve such a wide range, three methods are available:
The zoom ratio is 1: 6.5 with our variable magnification lens standard type (SDS – M).
In other words, a wide range of 1 to 1000 times physically is impossible.
However, the cameras used in our microscopes utilize a C-mount, which is a common standard, making lens replacement straightforward.

High Magnification Zoom Lens: SDS-FZR
Mount: C-Mount
Compatible Cameras: 1/2, 1/2.5, 1/3 Inch
Working Distance: 95mm
Magnification: 40x to 240x *2
*2 When mounted on our 1/2-inch camera and observed on a 17-inch monitor
However, changing the lens necessitates a review of the illumination setup.
Especially for observations at ultra-high magnifications like 1000x, substantial brightness in illumination becomes essential.
We have lenses and illumination available that exceed 1000x magnification, as follows:
Ultra-High Magnification USB Microscope: NSH130CS-R
Total Magnification: 200x to 1450x
2. **Objective Lens Exchange System:**
Since the consideration of implementation, it has been possible to choose a zoom lens with an interchangeable objective.
Originally, the microscope comes with a standard 10x objective lens,
resulting in a comprehensive magnification range of 200x to 1450x.
We have prepared the following optional objective lenses, allowing you to replace the standard 10x objective lens and achieve a wide magnification range.
Option: 2x Objective Lens QM Plan Apo L2 (2X)
Magnification: 40x to 240x
Option: 5x Objective Lens QM Plan Apo HL (5X)
Magnification: 100x to 600x
3. Simultaneous Use of Optional Lenses
The standard lens provided by our company is:
Standard Lens: SDS-M
Mount: C-Mount
Compatible Cameras: 1/2, 1/2.5, 1/3 Inch
Working Distance: 90mm
Magnification: 20x to 120x *1
*1 When mounted on our 1/2-inch camera and observed on a 17-inch monitor
By using the following optional 0.5x lens in conjunction with this front lens,
the magnification range can be extended to 15x to 90x.
0.5x Auxiliary Lens: TG-0.5
*To be inserted at the current lens’s leading edge.*
In this case, along with a reduction in magnification, the focal length will change from 90mm to approximately 170mm.
If the height of the pole is insufficient, we also offer extension poles.
By using the following optional 2x lens in conjunction,
the magnification range can be expanded to 60x to 360x.
Extender (x2): RCS-20
*To be placed between the camera and the current lens.*
In this case, the magnification will decrease, but the focal length will remain at 90mm.
*However, it is not highly recommended to adopt this method.*
Using auxiliary lenses to stack lenses may lead to various issues. While reducing magnification may have minimal impact, increasing magnification presents optical challenges such as:
– Darkening, requiring an increase in illumination.
– Pronounced color aberrations and reduced lens resolution at higher magnifications.
Therefore, it is advisable to consider the methods outlined in options ① or ②.
