L-Band Polarization-Insensitive Optical Isolator
Flyin Optronics’ Optical 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 high power handling capability. The devices are characterized with high performance, high reliability and low cost. It has been widely used in EDFAs, Raman amplifiers, DWDM systems, Fiber lasers, transmitters and other fiber optic communication equipments to suppress back reflection and back scattering.

Optical Isolator OIS9012-532 Fiber Optic Isolators U-optic
Dimensions: 12.7 mm × 12.7 mm × 12.7 mm Design Wavelength: 532 nm Material: K9 + Quartz Crystal
The optical isolator consists of a polarizing beamsplitter prism and a zero-order 1/4-wave plate, with the waveplate optical axis positioned at 45 degrees. Transmitted P-polarized light becomes circularly polarized after passing through the waveplate. After reflection and a second pass through the waveplate, it becomes S-polarized light and is reflected by the polarizing beamsplitter prism, providing optical isolation.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
