The ISO-04-850-MP Faraday Optical Isolator is essentially a uni-directional light valve. It is used to protect a laser source from destabilizing feedback or actual damage from back-reflected light. This 850 nm medium power free space optical isolator is packaged in a compact cylindrically shaped magneto-optic device with a base plate for ease of mounting into an optical train. It has a 4 mm clear aperture and a 800 to 900 nm wavelength range. The ISO-04-850-MP uses a higher damage threshold BK-7 polarizing beamsplitter (PBS) and provides double escape ports for applications where rejected power exceeds 0.5 W.
