Optolong UV/IR Blocking Filter and Protective Glass D=60 mm for CMOS cameras

Optolong D60 UV-IR Blocking Filter and Protective Window

This "filter" protects the sensor of your camera from dust and moisture and additionally functions as a UV/IR blocking filter.

This also allows astrophotography with refractors or telescopes with correctors, such as Newtonians with coma correctors or RCs with correctors. Blurring due to different focus positions of the IR light is thus prevented.

Note: With only reflective optics, infrared can be photographed without loss of sharpness, so a clear glass filter is then an alternative that allows a brighter image.
