With all-dielectric Ion Beam Sputtered coatings, TECHSPEC® High Power Nd:YAG Laser Mirrors provide reflectance up to 99.9% at 45° incidence. UV-grade fused silica mirror substrates are polished on both sides, which allows user to monitor transmitted light leakage through backside in demanding laser applications. Available in 0.5, 1.0, and 2.0 in. diameters, mirror models include YAG fundamental at 1064 nm, second harmonic at 532 nm, and UV versions at 355 and 266 nm.
