Infrared Lenses
SWIR MWIR LWIR
Illumination outside the visible spectrum is used in a wide variety of sectors including defense, security/surveillance, industrial, medical and R&D. Applications include tracking/targeting systems, predictive maintenance, monitoring of high temperature industrial processes, thermography, flame detection, quality control / inspection.
Opto Engineering® offers a wide variety of high-resolution IR optics for both cooled and uncooled IR cameras spanning all IR spectral bands.
MWIR and LWIR thermal series also include HCAR coating for use in harsh environments. Our offer also includes C-mount lenses for up to 1” detectors, optimized to work with ultraviolet illumination (365 nm) for high quality reflected UV imaging application.
