This unique filter consists of a two piece optically coated substrate designed to block the visible output of a light source from as close as 3 feet. Transmittance is ≤1.0% average from 400 to 890 nm and ≥65% average from 950 to 2500nm. Reflectance is ≤5.0% average from 400 to 700 nm. It is ideally suited for use with night vision equipment or CCD cameras for short or long range surveillance applications.
Typically used with infra-red cameras, scopes, and night vision goggles for surveillance, these filters enable infrared energy to be emitted from a variety of light sources while blocking visible energy, avoiding detection by the unaided eye.
