Wuhan Especial Optic' Ø1/2", Ø1", and Ø2" N-BK7 High Precision Windows are available uncoated 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: -A (350 - 700 nm), -B (650 - 1050 nm), or -C (1050 - 1700 nm). While uncoated windows have typical losses of about 4% per surface, the AR coatings reduce this to Ravg < 0.5%. These AR coatings provide good performance for angles of incidence (AOI) between 0° and 30°.
For applications that require protecting a laser output while minimizing stray light and reflections, we offer this line of laser windows. Each side of the optic features an AR coating that is centered around a common laser wavelength. These windows also exhibit high damage thresholds, making them an ideal solution for most industrial and laser protecting applications.
