Newport MKS Dielectric Mirror, Broadband, 12.7 mm Diameter, 488-694 nm 05D20BD.1

The 05D20BD.1 Broadband Dielectric Mirror is an extremely versatile mirror for laboratory applications and highly efficient over a broad wavelength range. This 1/2 inch (12.7 mm) diameter mirror is made from a 3.1 mm thick Borofloat® 33 substrate. Borofloat® 33 has low thermal expansion and is an excellent substrate for most applications. The BD-1 coating is extremely durable and will withstand repeated cleaning. This mirror has a λ/10 surface flatness and a 15-5 surface quality. This product is also available in 10-piece saving pack . Borofloat® 33 Substrates Borofloat 33 is a high quality borosilicate glass that offers low thermal expansion and high thermal shock resistance. Its material properties and moderate cost make Borofloat 33 an ideal substrate for general purpose applications. For more information, please see our Optical Materials technical note. Visible Broadband Dielectric Coating Our BD.1 visible broadband dielectric coating reflects all visible laser lines in the range of 488 to 694 nm with greater than 99% efficiency for s-polarization and 98% for p-polarization at 0 - 45° angle of incidence.
