These Pockels cells offer a voltage contrast ratio that is greater than 8000:1 at 1064 nm. Featuring axially adjustable windows for sub-millimeter control of window/crystal spacing and 224 TPI differential screws for arc-second adjustment of windows parallelism or net wedge.
The TX series represents the most advanced large aperture optical isolators commercially available and incorporates state-of-the-art features, such as specially modified cylindrical-ring electrode geometries for optimum aperture extinction and transmission uniformity and minimum optical path length.
