Newport’s Ultra-broadband mirrors are IBS coated with special design with layers of dielectric materials to use for high reflection and high damage threshold in a wide wavelength regime. BB.1 coated mirrors covers the UV to visible wavelength regime (350-700nm) while the BB.2 coated mirror covers the visible to near IR wavelength regime (650-1130nm) and BB.3 coated mirror covers the UV to near IR wavelength regime (350 - 1100 nm). UV grade fused silica is used as a substrate material for these mirrors for low thermal expansion and low material absorption in the wavelength regime of 350-1200nm.These mirrors will perform with relatively high energy pulses and will have better resistance from environmental effects compared to many other metallic and dielectric mirrors used in these wavelength regimes. For low damage threshold and relatively smaller broadness requirement please our economical Broadband Dielectric Mirrors. For Ultrafast laser pulse use our Low GVD Super-Broadband Turning Mirrors for Ultrashort Pulses.
