Description
The Faraday Rotator (TGG Type) Core from Ascentta, Inc. is engineered for high-performance optical isolation and rotation in precision photonic systems operating at key wavelengths from 532 nm to 1064 nm. Utilizing Terbium Gallium Garnet (TGG) crystal, this non-reciprocal optical device offers stable and consistent Faraday rotation under various environmental conditions. With ultra-low insertion loss (typ. 0.25 dB) and a high extinction ratio (min. 28 dB), the rotator is ideal for use in laser systems, amplifiers, and optical isolators.
Its robust design supports operation over a wide temperature range (10°C to 50°C) and power levels up to 5 W, making it suitable for demanding applications in research, telecommunications, and industrial laser systems. Offered in a range of clear apertures and mechanical sizes, Ascentta’s rotator cores are customizable to meet your exact system requirements. Make inquiries for bespoke configurations to match specific wavelength, power, or dimensional needs.
