Product Description

Customized Free Space Optical Isolator

Polarization free space isolators are essential components in high-speed optical transmitters and pump laser systems requiring backward light isolation. These isolators deliver exceptional performance with high isolation levels and minimal insertion loss.

Available Configurations

Available in single stage or semi-double stage options centered at 1310nm, 1490nm, or 1550nm wavelengths. Standard clear aperture diameters range from 0.40mm to 1.5mm with packaging options including square, round, or U-shaped housings.

Key Features

Superior performance and reliability
Customized size and wavelength options
High isolation with low insertion loss
Low, medium, and high power configurations

Primary Applications

Maintain light's linear polarization
Reduce Nd and Yb oscillations from ASE created by amplifiers
Prevent deleterious effects of back reflections in laser diodes
Eliminate instability in amplified laser systems caused by ASE
