The 1.25″ IR Pass Filter is suitable for infra red (IR) sensitive cameras.

Typically the infrared wavelength is taken to extend from the nominal red edge of the visible spectrum at 700 nanometers to 1 millimeter.

This ZWO filter will allow the light spectrum from 850nanometers to pass through the filter into the optics or camera.

Key features:

• For use with ZWO ASI IR sensitive cameras
• 1.25″ round filter with a threaded attachment.
