N-BK7 High Precision Windows exhibit high transmission for the 350 nm - 2.0 μm range or with one of our three low-loss standard broadband antireflection (AR) coatings deposited on both surfaces: 350 - 700 nm, 650 - 1050 nm, or 1050 - 1700 nm. While uncoated windows have typical losses of about 4% per surface, the AR coatings reduce this to Ravg < 0.25%. These AR coatings provide good performance for angles of incidence (AOI) between 0° and 30°.
