The 10B20BB.3 is an Ultra-broadband Dielectric Mirror with a 25.4 inch diameter, 6.35 mm thickness, and absolute Reflectivity > 99% at an AOI of 0-50°, from 350-1100 nm. Newport’s Ultra-broadband mirrors are IBS coated with layers of dielectric materials to use for high reflection and high damage threshold in a wide wavelength regime. The BB.2 coated mirror covers the visible to near IR wavelengths (350-1100 nm).
