Opto Engineering LWIR

Long-wave infrared lenses

The LWIR series from Opto Engineering are a range of long-wave infrared lenses specifically designed to operate in the 8-14 μm wavelength range with uncooled detectors.

The lenses are designed with high image quality and large aperture (small F/#). These lenses can also be requested with custom mount interfaces.

These lenses, are the perfect choice for a variety of applications, including temperature measurement for process quality control, predictive maintenance and medical imaging to give a few examples.
