Opto Engineering SWIR - Infrared optics made for high resolution detectors

Opto Engineering SWIR is a family of shortwave infrared lenses specifically designed to operate in the 0.9-1.7 ?m wavelength region. This series has been specifically designed to match the new 15 ?m format InGaAs FPA Focal Plane Arrays. The lenses offer an industry standard C mount threaded style interface or, alternatively, they can be equipped with a custom mount interface at no additional cost.

In the design of the lenses, great importance was attached to a good image quality and a large aperture (small F-number). These lenses, mounted on a SWIR camera, are the perfect choice for a variety of applications, including solar cell inspection, night vision imaging of outdoors scenes without additional illumination (security applications), detecting bruises on fruit, imaging through silicon, biomedical imaging and many other infrared applications.
