Optical Interface
The distance of the lens installation reference plane to the sensor photosensitive surface, the acceptable
lens thread length, and filter/substrate information are in the table below (if you need other lens interfaces,
please contact sales or technical support for information). The cut-off frequency of the visible light filter of
the color camera is 700nm, which reduces the impact of the invisible part on the image. The filter/substrate
has an impact on the rear focus, and removing it may cause unclear focus. If it must be removed, please
contact our technical support.
