ZnSe meniscus lenses (ZnSe CVD). Catalog of ZnSe meniscus lens.

Zinc Selenide Meniscus Lenses are used in thermal imaging, FLIR, and medical systems in the 600nm to 16000nm range. ZnSe Meniscus lenses can be made from IR or Laser Grade ZnSe depending on application. AR coating for 10.6, 8-12 or 2-13 microns are available upon request.

Custom ZnSe Meniscus lenses are available in any size and focal length.
