BBAR Coatings

Broadband AR coatings operate usually at lower efficiency than V-Coatings, but they provide anti-reflective properties over much wider spectral range. Spectral performance of a typical visible AR coating designed for BK7 glass is shown in the figure below.

10 ns pulse, 20 – 30 Hz lasers, measured anywhere between 1310 and 1650 nm.
In addition to UV, visible, and NIR BBAR coatings our lab is known for very high quality, high laser damage threshold AR coatings that operate over 1.5 – 5.0µ.
