1064nm Polarization Insensitive Optical Isolator-300mW
1064nm Polarization Insensitive Isolator utilizes Faraday Effect of Magneto optical crystal. It guides optical light in one direction and eliminates back reflection and back scattering in the reverse direction at any polarization sate. The unique manufacturing process and optical path epoxy-free design enhance the device’s excellent environmental stability and reliability. The devices are characterized with low insertion loss, high isolation, high return loss, low cost. It has been widely used in EDFAs, Raman amplifiers, Fiber lasers, transmitters and other fiber optic communication equipments to suppress back reflection and back scattering.
If you do not see a standard isolator that meets your needs, we welcome the opportunity to review your desired specification and quote a custom isolator. Requests for custom fiber pigtails, different wavelengths and handling power of operation or other specific needs will be readily addressed.

- Above specifications are for device without connector.
- For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower. The default connector key is aligned to slow axis. Power transmits through the connector less than 2W.
- For this 1064nm Isolator, Due to high IL, it is recommended to use average power of <300mW for single stage and <200mW for dual stage. If you need higher handle power, please look for our 1064nm TGG High power isolator.
- If there is pulse application, please be sure to inform us of pulse energy and peak power.
