Faraday Optical Isolator, Compact, 4 mm, 785 nm, PM Isolator, 1/2 Waveplate
Model: ISO-FRDY-04-785-W
Product Series Overview
Compact Faraday Optical IsolatorsThe ISO-FRDY-02-785-W Compact Optical Isolator is essentially a uni-directional light valve. It is primarily used for elimination of frequency instability in single frequency lasers such as laser diodes and OPSLs, the prevention of mode-hopping in external cavity diode lasers, and the elimination of parasitic oscillations due to ASE in amplified laser systems. The compact design makes it highly suitable for OEM integration. It has a 2 mm clear aperture and a 775 nm to 795 nm wavelength range. The ISO-FRDY-02-785-W contains optically-contacted polarizing beam splitter cubes resulting in high transmission as compared to other available isolators. This -W version has an added 1/2 wave plate at the output stage.
High Transmission Polarizing Beamsplitter Cube
Our compact isolators contain optically contacted polarizing beamsplitter cubes that provide high transmission. With more photons available for your application, diodes can be run at lower currents, extending the diode lifetime.
1/2 Waveplate Option
We offer versions with an added zero order 1/2 wave plate (-W models). The waveplate is installed at the factory and cannot be adjusted. Should you need to adjust the waveplate please contact us.
