Alluxa’s Ultra Series of high performance filters now includes our Ultra-Narrow UV Filters. These ultra-narrow filter capabilities are both deeper into the UV and narrower in the VIS/NIR. Our current designs include a 266 Narrowband four cavity filter designed to improve spectral fidelity of a 266 laser, the highest transmission narrowband filter available today. Applications such as LIDAR, Research, Astronomy, Fusion Research, and Instrumentation will greatly benefit from this line of UV filters.
