LightPath Technologies Inc. has introduced athermalized f/1.0, 10.63-mm-focal-length long-wave infrared lens assemblies for thermal imaging using 8- to 12-µm infrared signatures. Designed for uncooled infrared sensors, the lenses are the primary optics for thermal imagers in homeland security, firefighting, predictive maintenance and drivers’ vision enhancement systems in automobiles. The assemblies integrate proprietary Black Diamond molded chalcogenide infrared lenses that are a lower-cost substitute for high-volume diamond-turned germanium and zinc selenide optics. The material properties of the Black Diamond glasses provide natural athermalization for temperature stability from 25 to 75 °C. The design yields a 52° field of view when paired with a 10-mm sensor with a 25-µm pixel pitch.
