64-470 50 mm Dia. High Performance Dielectric Hot Mirror; 45 deg AOI 400-1150nm

The 64-470 is a high-performance dielectric hot mirror, designed and manufactured by Edmund Optics. This circular filter, with a diameter of 50 mm and a thickness of 3.3 mm, is specifically engineered for a 45-degree angle of incidence (AOI) and operates within the wavelength range of 400-1150nm.

The mirror's front and back are coated with EDM 64-463, a proprietary dielectric coating that enhances its reflective properties. This coating is designed to reflect infrared light while allowing visible light to pass through, making it ideal for applications that require the separation of these two spectral regions.

The 64-470 is shaped as a thin lens, which contributes to its high optical quality and minimal optical aberrations. It is made from borofloat33, a borosilicate glass known for its excellent thermal stability and chemical resistance. This makes the mirror suitable for use in various environments and applications.
