Free-Space Isolator SIS3-405-1.5W
An optical or Faraday isolator is a passive magneto-optical device transmitting light in one direction while blocking back-reflections from upstream optics. It protects sources and systems from reflected noise and interference and improves power stability. Input polarizer, Faraday rotator, and output polarizer form the isolator, with polarizers at 45°. Forward light is filtered into linear polarization, rotated 45°, and transmitted through the output polarizer. Reverse light undergoes rotation in the same direction, reaching 90° relative to incident polarization and becoming perpendicular to the input transmission axis, so it is blocked. JCOPTIX free-space isolators offer center wavelengths covering 405-1064 nm. Contact technical support for custom apertures, wavelength ranges, packages, or polarizers.

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.
