Faraday Optical Isolator, Mid-IR, 4 mm Aperture, 2050 nm Center
Model: ISO-FRDY-04-2050-N
Product Series Overview
Mid-IR Faraday Optical IsolatorsThe ISO-FRDY-04-2050-N Faraday Optical Isolator is essentially a uni-directional light valve for Mid-IR Lasers. It is used to protect a laser source from destabilizing feedback or actual damage from back-reflected light. This 2050 nm high 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 2000 to 2100 nm wavelength range. Horizontal input and 45 degree clockwise polarization output.
High Efficiency Performance
The YIG crystal utilized in our Faraday isolators creates a large Verdet constant that ultimately describes the strength of the Faraday effect and provides effective isolation of back-reflected light. Additionally, these isolators have low absorption as a function of the YIG crystal and polarizers, resulting in reliable transmission of light in the forward direction.
1/2 Waveplate Option
We offer versions with an added zero order 1/2 wave plate (-W models) at the output stage so that the direction of the output beam polarization can be rotated to a desired direction.
