For over 30 years, Ophir Optronics is the world leader in designing and manufacturing optical elements and lens for cooled camera, 3-5 micron. Ophir leverage this vast experience, offering off-the-shelf, predesigned, Single, Dual, Tipple Filed Of View lenses, as well as progressive zoom lenses. Several of Ophir’s 3FOV lenses and Zoom lenses are equipped with multiplier, extending the focal length of the lens without compromising the F#. For increased flexibility, Ophir design it’s lenses for cooled FPA for both 19.6 mm and 25.4mm cold shield (Cold Stop to FPA Distance).

With the largest offering of lenses for uncooled infrared camera, Ophir offers it’s customer best solution for and Night Vision applications. Our experience working with the majority of the FPA manufactures and infrared systems integrators around the world enable us introducing off-the-Shelve and custom-built lenses that will best suit your need. Ophir lenses for 8-12 microns FPA are available in variety of focal length starting from 4mm to 342mm, Zoom lenses, manual, fix, and motorized focus mechanism.  Different F/# enable the customer selecting the best fit to his application according to lens size, weight, and performance. Dual FOV and Zoom lens are also available extending the system capabilities to more applications and use. Owning all lens design and manufacturing technologies in house enable Ophir Optronics customized existing lens of design a new lens to best fit your needs.

For the last 8 years, Ophir specialized in designing and manufacturing lenses for Radiometric/Thermograph systems. The majority of Ophir lenses are design for 8-12 microns, Long Wave Infrared (LWIR) Bands, however with unique coating developed in Ophir, 3-12 micron band is also available. Varity of focal length and F/# are offered by Ophir fitted to different applications varying in image quality, lens weight and cost. Ophir also offer fix and manual focus capabilities and its unique passive athermalization capability, keeping the image in focus over wide range of environment temperature changes.

In many FLIR applications the need to maintain focus over wide change of the environmental temperature is essential to the system performance and usability. Ophir specialized in design and manufacture of passively athermalized lenses. The optic and the mechanical design of the lenses will maintain the focus position passively, without power, during changes in the environment temperature between -40 degrees to +80 degrees Celsius.

Ophir manufactures complete lens assemblies designed to satisfy stringent optical, mechanical and environmental performance specifications. Ophir optical design team possesses wide knowledge in designing lenses for MWIR and LWIR cameras and lenses for Thermograph applications. Ophir Optronics mechanical engineering team is a would leader in designing the lens mechanics, specializing in manual and motorized focus mechanism, passively athermal lens design, and supporting low weight, rugged, or high pressure sealing requirements. Ophir Dual and Triple FOV, and Zoom lenses are also equipped with in house designed electronic controller to maintain FOV and focus positions.
