1310/1480/1550nm Polarization-Independent Optical Isolator
An optical isolator transmits light in one direction and effectively blocks light reflected back through the fiber. Isolation measures its ability to block this return light. Isolators are commonly used in optical paths to protect sources, pump sources and other light-emitting devices from interference and damage caused by back-reflections. Types include in-line and free-space isolators; Shanghai Hanyu supplies various specifications for different applications. Its 1310/1480/1550nm polarization-independent isolators internally process the two orthogonal polarization states in single-mode fiber separately to ensure polarization-independent operation. Single-stage devices offer lower insertion loss, while dual-stage devices provide very high isolation for different applications.

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.
For low-frequency RF, electromagnetic testing and power combining systems, conventional resistive power dividers bring high insertion loss, while standard directional couplers cannot provide equal-amplitude signals with 180° phase shift. They fail differential circuits, balanced amplifiers and signal cancellation systems.
