Heat-Reflecting Hot Mirrors
Heat-Reflecting Hot Mirrors
Hot mirrors are heat-reflecting mirrors that are designed to work as a shortpass edge filter by transmitting visible wavelengths at a 0° angle of incidence, while reflecting near-infrared, heat-generating wavelengths.
- Remove unwanted heat from an optical system
- Reflect NIR heat & transmit VIS light at 0°
- 25.4 mm diameter or 50.8 mm square filters See All Features
