1kW Free Space Optical Isolators 1550nm

SKU: OIHF

The OIHF series optical isolators are engineered for kilowatt-class, single-polarization laser systems and feature Agiltron’s proprietary configuration with advanced compensation technologies for thermal lensing and wavelength shifts under high optical radiation. These isolators offer broadband performance, delivering >40 dB isolation over 100 nm and >30 dB over 300 nm, with power handling proportional to aperture size — requiring beam expansion and collimation to match the aperture to reduce power density. Covering a wide spectral range from 450 nm to 2450 nm, the standard configuration is centered at 1550 nm, with an optional built-in output tap monitor. For a 1550 nm laser, the largest aperture size is 10 mm, while for 1060 and 980 nm short wavelength laser, the max beam size is 30 mm
