Thermal Imaging Assemblies

Infrared Optics

Infrared lenses designed for thermal imaging cameras operating in the mid-wave and long-wave infrared (MWIR, LWIR) bands, for applications such as thermography, diagnostics, security and surveillance.

    LightPath’s infrared lens assemblies are a cost effective replacement for traditional diamond turned infrared lenses. LightPath’s molded lenses provide exceptional value for high volume applications and are coated and assembled into threaded housings.
