Elliptical mirrors are designed to present a circular mirror profile when mounted at a 45 degree angle. Round mirrors mounted at 45 degrees can't maintain a circular profile and may allow for parts of the beam to not be reflected. As a result elliptical mirrors are ideal for periscopes and other 45 degree beam routing applications.
Our DM.11 multilayer dielectric coating is optimized for the 2nd harmonic 532 nm Nd:YAG laser line. It offers greater than 99% efficiency for s-polarization or p-polarization at 0-45° angle of incidence.
Our DM.10 multilayer dielectric coating is optimized for the 1064 nm fundamental harmonic Nd:YAG laser line. It offers greater than 99% efficiency for s-polarization or p-polarization at 0-45° angle of incidence.
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.
All dielectric coating construction is physically more durable than standard metallic coatings. Dielectric mirrors are more resistant to humidity, thermal changes, abrasion and salt exposure. They can also withstand repeated cleaning.
