NIR BBAR Windows

Precision Optical System’s NIR-BBAR Windows are optically polished glass windows with a high efficiency broadband anti-reflection coating designed for maximum transmission throughout the Near-IR spectrum.

For comparative purposes, an uncoated glass window with negligible absorption losses only transmits approximately 92% of the light due to reflection loss (4% reflection loss from each glass/air surface). Our NIR-BBAR coating reduces reflection loss to less than a 1.0% average from 400-1100nm per surface, resulting in superior light transmission.

We utilize state-of-the-art ion assisted deposition to produce a tough, durable coating, suitable for harsh environments, which are able to withstand repeated handling and cleaning.
