MARS-U3 cameras are equipped with C-mount lens adapters. The back-flange distance is 17.526 mm (in
the air). The maximum allowed thread length of lens should be less than 11.1mm, as shown in Figure 5-2.
A longer lens thread will damage camera.
The color models are equipped with an IR filter and the cut-off frequency is 700nm. The mono models are
equipped with a transparent glass. Remove IR-filter or transparent glass will defocus the image plane.
Contact our technical support when the glass needed to be removed.
