Description

Ascentta’s Single-Mode Polarization-Insensitive TGG Optical Isolator is engineered to deliver stable, high-performance isolation for optical systems that operate in the visible and near-infrared range. Standard models are available for popular wavelengths such as 532 nm, 635 nm, 650 nm, 780 nm, 850 nm, 980 nm, 1030 nm, and 1060 nm. We can also manufacture for customized wavelengths within this range to meet unique application needs. By blocking back reflections and feedback, the isolator helps protect light sources and maintain signal quality in systems used for fiber communications, biomedical imaging, photonics research, and optical sensing.

This isolator features a single-mode, polarization-insensitive design that ensures consistent performance regardless of the input light’s polarization state. Each unit is built with precise optical alignment and excellent long-term stability, making it a reliable component for integration into lasers, interferometers, optical amplifiers, and precision measurement instruments.

Because every optical setup has different requirements, the TGG isolator can be tailored to specific needs. Options include custom wavelengths, fiber types, cable jackets (bare fiber, loose tube, or 3mm cable), connectors (FC/APC, FC/PC, SC/APC, LC/APC, or other), and fiber lengths. Whether it is used in a telecom network, an industrial laser process, a diagnostic instrument, or a laboratory prototype, this isolator can be configured for seamless integration and dependable performance in demanding environments.
