Precision Optical System’s VIS-BBAR Windows are optically polished glass windows with a high efficiency broadband anti-reflection coating designed for maximum transmission throughout the visible 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 VIS-BBAR coating reduces reflection loss to less than a 0.5% average from 425-675nm per surface, resulting in superior light transmission.
We utilize state-of-the-art ion deposition methods to produce a tough, durable coating, suitable for harsh environments, which are able to withstand repeated handling and cleaning.
