This high performance, utility-sized isolator economizes on space requirement while utilizing novel design features that greatly reduce production costs, thus enabling a selling price that is far below competing products.

Our Mid-IR Optical Isolators eliminate the annoying effects of feedback in laser applications and systems, operating at specific wavelengths from 4 μm to beyond 14 μm.
