NOTES:
1. Filter mount and retaining ring are black anodized aluminum.
2. This threaded filter screws into any C- or CS-mount camera so it is positioned
directly in front of the sensor. Wrenching slots on the retaining ring aid in
threading the filter into the camera body. A lens spanner wrench, pointed object
or the upper anvils of a pair of vernier calipers can be used as wrenching tools.
After installing the filter, the lens is threaded into the camera and the filter then
sits immediately behind the lens.
3. Do not scale drawing. All dimensions are in mm.
