Request InfoAlluxaAlluxa’s Ultra-Narrowband filters, for applications such as laser cleanup, lidar, telecommunications, and instrumentation, offer the narrowest and most square filter profiles in the visible and NIR. The high transmission levels are typically greater than 96% at the targeted wavelength. Unlike narrowband filters made with other deposition technologies, our ultra-narrowband filters offer wide and deep blocking performance at levels up to and beyond OD6 without sacrificing transmission performance.
