OFR has been in optical isolators from the beginning. In fact, OFR introduced the optical isolator to the world's photonics market. Having designed more than 100 models in response to customers' requirements since the early 1980s, OFR now produces more isolator models than any other manufacturer. With a 35-year history, OFR became a division of Thorlabs in January 2007. Shortly afterwards, the OFR group began a rapid expansion of its optical isolator production facilities with support from a team of Thorlabs lean manufacturing experts. Driven in large part by the growing demand created by the rapid expansion of the fiber laser market, we are now producing significant volumes of optical isolators. To further develop our capabilities, in June 2008 we completed the installations of precision thin film coating facilities. OFR's new coating facility will support the expansion of its world-class line of optical isolators and provide the flexibility needed to expand its on-demand production capabilities of custom or OEM optical isolators.

Faraday Rotator crystal rods are optically ground and polished in the OFR optical shop using OFR-designed tooling. End faces of the rotator rods are ground and polished to <5 arc seconds parallel. Thus, end-face specifications are maintained under OFR control. This, along with internal inspection (for inclusions and strain-birefringence) of 100% of all Faraday Rotator crystal rods used, insures that all Isolators meet OFR's discriminating specifications.

OFR manufactures Faraday Optical Isolators for virtually all lasers from 193 nm to 10.6 µm and beyond. Most models are available with low-power or high-power polarizers. All are permanent magnet, single-pass type Isolators.
