Broadband mirror 10Q20BB series

dielectricfused silicalaser

Ultra-Broadband high reflectors are ideal for applications such as photon counting, hyperspectral imaging or Raman Spectroscopy. •RS, RP >99% @ 350-700 nm, 610-1130 nm, or 350-1100 nm •Substrate flatness & surface quality λ/10, 20-10 •Available in diameter 25.4 mm •High performance all dielectric coating •Designed to work for 0-50 degrees angle of incidence Features UV Fused Silica Substrates Fused Silica is synthetic amorphous silicon dioxide of extremely high purity. This non-crystalline, colorless silica glass combines a low content of inclusions with high refractive index homogeneity, a very low thermal expansion coefficient, and excellent transmittance in the wavelength regime from UV to NIR. As a result, these mirrors will perform better with temperature fluctuations and is ideal for high-energy laser applications due to its high energy damage threshold. For more information, please see our Optical Materials technical note. Wide Wavelength Range With High Absolute Reflectivity Using superior ion beam sputtering coating technology, very high absolute reflectivity can be achieved across a large wavelength range. It is advantageous in low light situations when it is critical to collect as much light as possible. Depending on the coating type, you will have as much as RS, RP >99% for 350-1100 nm at 0-50° angle of incidence. UV-VIS Broadband Dielectric Coating BB.1 coated mirrors covers the UV to visible wavelength regime from 350 to 700 nm VIS-NIR Broadband Dielectric Coating BB.2 coated mirror covers the visible to near IR wavelength regime from 610 to 1130 nm
