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.
Features
- High transmission for the visible light range
- High reflection of infrared
