Temmek Optics designs and manufactures long-wave and medium-wave infrared lenses. Temmek's Infrared Lens line includes continuous zoom, discrete zoom, and fixed-focus lens assemblies. Temmek's products are designed to operate with cooled and uncooled detectors, with fast customization to the customer's detector, both optically and mechanically. Temmek manufactures the mechanical and optical technologies in-house. This expertise is incorporated into Temmek's designs and allows for very short time-to-market of prototypes and a swift prototype-to-production transition. Temmek Optics is part of the Gal Shvav Industrial Group.
