IdealPhotonics' UV free-space optical isolator is an optical device specifically designed for the ultraviolet band. Its core function is to allow unidirectional light transmission (e.g., forward-incident light passes through while backward-reflected light is blocked), thereby protecting sensitive ultraviolet light sources (such as excimer lasers) from interference or damage caused by back-reflected light.Based on an ultraviolet-optimized magneto-optical/polarization modulation mechanism, it achieves high isolation (>30dB) unidirectional transmission in the deep ultraviolet band (200-400nm), combining laser damage resistance with low insertion loss characteristics, and is specifically designed to protect sensitive UV light sources.
