Optical Front End Procedures
3.6.1. Window Removal and Replacement Procedure
TSI Cooled sCMOS cameras have a protective clear glass window installed (See Section 3.5.1). The window has
a broadband anti-reflection coating that is easily scratched or smudged by oil from fingers. Use soft, clean cotton,
latex, or nitrile gloves and handle the window by the edges.
The optical front end is designed to accommodate standard Ø1" windows. Users can, at their discretion, operate
the camera without any glass installed or install custom filters in front of the sensor. The maximum filter thickness
when using the C-mount adapter is 0.079" (2.0 mm). See Chapter 6 for more information on both types of windows.
Note:
If no glass is installed, dust and debris may collect on the hermetic chamber window. Care must be taken
when cleaning this window to avoid scratching or other damage to the glass. Please use every precaution to avoid
contact with the hermetic chamber window, and to keep the camera securely mounted to the optical system or
capped when not in use.
Removal of the Protective Window from the Camera
1. Using the hex key provided, remove the three socket head screws from the C-mount adapter.
2. You can now lift the C-mount adapter out of the camera housing.
3. Locate the pry slot along the perimeter of the rubber O-ring that is holding the protective window in the
adapter. Using a non-metallic tool (optic safe tweezers or equivalent) pry the O-ring out of the C-mount
adapter. Use caution to prevent the glass window from falling out of the adapter.

Removing the Window
4. Carefully remove the window from the C-mount adapter and place it in a safe location.
3.6.2. Re-Assembly of the Window and C-Mount Adapter and Flange Focus Adjustment
1. Replacement of the window and C-mount adapter is done in the reverse order as shown in Section 3.6.1.
Care must be taken when handling the window.
2. The O-ring used to secure the window in the adapter must be pressed firmly into the mating groove in the
adapter until both the O-ring and the window are held securely in place.
3. Clean the window prior to reinstalling the C-mount adapter into the camera.
4.
Install a compatible lens. There is no further adjustment required as the C-mount adapter has a fixed flange
focal distance.
