The ISO-04-461-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 461 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 400 to 500 nm wavelength range. The ISO-04-461-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.
