ASI D21 IR/UV Cut Filter - protective window
This filter protects the sensor of your camera from dust and moisture, but preserves its spectral response in the visual range very well.

If you are using optics with refractive elements (like lenses), this IR blocking filter prevents losing sharpness, as UV and IR have not necessarily the same focus as visible light.

Note: With all-reflecting telescopes, IR radiation can be recorded without sacrificing sharpness, so a clear glass filter might be an alternative which give higher brightness.

This protective window fits, among others, to the the following ASI cameras:
ASI 120 cameras (recommended mainly for 120MC and 120MC-S)
ASI 224MC camera (uncooled)
ASI 385 cameras (uncooled)
ASI 290 cameras (also MINI)
ASI 178 cameras (uncooled)

Diameter:21 mm
Minimum transmission from 425 nm to 670 nm:90%
Thickness:1.1 mm
Cell:no (unmounted)

"Da das Original Fenster der Asi224 keinen IR Cut hat ist die Farbbalance bei All Sky Anwendung problematisch. Das IR cut Fenster löst dieses Problem."
