This covert filter design blocks energy with wavelengths shorter than 825nm.
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.
