Lens Mount
The xiQ cameras are compatible with C-mount and CS-mount lenses.
figure 3-1, position C/CS-Mount module B
The cameras are delivered with C-mount back focal length. By removing the “C/CS-Mount module B” (see the figure above) the
camera can be rebuilt to CS-mount compatibility. Effectively reducing the back focal distance and overall length of camera by
5mm. The required M2x8mm special screws are part of the camera delivery. The length of the lens thread is 6.5 mm. Please
read the chapter
carefully. Conversion between those two options is described:
https://www.ximea.com/support/projects/usb3/wiki/Convert_C_to_CS_Mount
Note: The distance between the threaded flange and the surface of the filter glass is 11.9 mm in case of C-Mount and 6.9 mm
in case of CS-Mount. To avoid damaging of the filter glass, nothing may extend deeper into the housing.
Lens mount adapter configuration:
•
C-Mount (with C/CS Mount module B)
•
CS-Mount (without C/CS Mount module B)
