Ophir Optics Group - Infrared Optics - Radiometric Lenses for uncooled cameras

For over a decade, Ophir Optics has specialized in designing and manufacturing lenses for Radiometric and Thermograph systems. The majority of Ophir Optics lenses are designed for Long Wave Infrared (LWIR), 8-12 microns. Their performance can be extended over both the MWIR and LWIR bands, from 3-12 microns using an unique, innovative anti-reflection coating developed by Ophir Optics. A variety of focal lengths and f/#’s are offered by Ophir Optics to serve a wide range of applications, image quality requirements, lens size and weight, and cost. Ophir Optics offers fixed focal length and manual focus lenses utilizing a unique passive athermalization solution that maintains focus over wide range of environmental conditions and temperature ranges.

Ophir Optics Group - Infrared Optics - Athermalized Lenses for uncooled cameras
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 Optics Group - Infrared Optics - Lenses for cooled cameras

For over 30 years, Ophir Optics has been a world-leading designer and manufacturer of complex lens assemblies through optical components for cooled MWIR (3-5 microns) cameras. Ophir Optics leverages vast experience to offer wide variety of lens systems available off-the-shelf: motorized zoom lenses, multiple field of view lenses (dual and triple) and fixed focal length lenses. Focal length multipliers are available for several of the zoom lenses and triple field of view lenses to extend the lens focal length while maintaining the original f/#. For increased flexibility, Ophir Optics offers lenses optimized for cooled FPA cold shield distances of 19.6mm and 25.4mm (cold stop to FPA distance).
