Fiber Accessories/Fiber Optic Sensors/FBG Accelerometer/200 Hz FBG Accelerometer
The polarization-dependent free-space optical isolator is a free-space isolator based on a TGG-type structure. It offers a selection of operating wavelengths from 532 nm to 1060 nm. With high isolation, low insertion loss, and high extinction ratio, it is suitable for unidirectional optical transmission and reverse light isolation in free-space optical paths. The product features a compact cylindrical housing and is available with multiple clear aperture sizes, power ratings, and outer dimension configurations, enabling selection and customization according to different optical system requirements.
Product features:Polarization‑dependent design;Free‑space optical path;High isolation;Low insertion loss;High extinction ratio
Part Number:MP-ISO-S-532-B-1.8
Application area:Laser optical path systems | Optical test systems | Reverse light isolation for lasers | Research laboratory optical setups
