Faraday Optical Isolator, Low Power, 4 mm Aperture, 780 nm Center.

The ISO-04-780-LP 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 780 nm low 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 740 to 860 nm wavelength range. The ISO-04-780-LP utilizes field proven, high efficiency Corning Polarcor™ polarizers; ideal for laser diode applications.
