ORLANDO, Fla., Feb. 17, 2010 – 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 a wide variety of applications including 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 Black Diamond glasses provide natural athermalization for temperature stability from 25 to 75 °C, without adding additional cost. This design yields a 52° field-of-view when paired with a 10-mm sensor with a 25-µm pixel pitch.
