Hot Mirrors
Abrisa Technologies can supply Hot Mirrors or short wave pass filters (SWP) for heat control applications. For Hot Mirrors, a thin film coating is applied to a glass substrate, such as soda-lime or borosilicate, in order to reflect infrared radiation either as a means to harness the reflected wavelengths for an application or remove them from an application. Simplified, a Hot Mirror will separate visible light from heat. Hot Mirrors are typically provided on a cut to order basis in thicknesses of 1.1 mm, and 3.3mm and in diameters up to 27”. Custom sizes and thicknesses and specialty designs are available upon request.
Hot Mirror Features
- High transmission for the visible light range
- High reflection of infrared
- Heat resistant borosilicate glass substrates – SCHOTT Borofloat®
- Thin film dielectric multi-layer coating
- Standard angles of incidence are 0 and 45 degrees
Hot Mirror Specifications
