Medium-wave infrared lenses

The medium-wave infrared lenses are specifically designed to operate in the 3-5 μm wavelength region with InSb Focal Plane Arrays (FPA).

These lenses are available with a standard Bayonet mount (with a back flange distance of 34.44 mm). The optics have good image quality and a large aperture (F/# 2.3).

With a high resolution (up to 15 μm pixel pitch) and 21 mm diameter, these lenses, mounted on a MWIR camera, are the perfect choice for a variety of applications, including imaging through fog, high-speed thermal imaging, thermography, R&D (MWIR range).
