638nm(300mW) Polarization-Maintaining Isolator
An isolator is a high-performance passive optical device that transmits optical signals in one direction, effectively blocks reflected light, and protects the laser source. It offers low insertion loss, high isolation, and high operating efficiency, with in-line and miniature packaging options. Its excellent environmental stability and reliability make it suitable for precision optoelectronic applications such as fiber lasers and optical communication instrumentation. Note: Ghfiberlight can customize isolators in various specifications according to customer requirements.

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.
