Polarization Maintaining Optical Circulator TGG based (532, 635, 680, 780, 808, 850, 930, 980, 1030, 1053, 1064, 1150nm)

Product Overview

Gezhi Photonics TGG-based polarization maintaining optical circulator adopts high-performance terbium gallium garnet magneto-optic crystal as the core component. It covers a wide wavelength range from 532nm to 1150nm, including visible and near-infrared common bands.

This PM circulator features ultra-low insertion loss, superior isolation, high extinction ratio and high return loss. It supports CW power handling from 0.5W up to 20W, and two polarization axis working modes (Type B dual-axis & Type F slow-axis only). Standard 70×28×26mm compact package is available, with fully customizable pigtail fiber, fiber length, connector type and pulse peak power. Ideal for fiber laser amplifiers, medical optical instruments and precision optical test systems.
