LightPath Technologies (Orlando, FL) has introduced an f/#1.0 athermalised long wave infrared (LWIR) lens assembly with 10.65mm focal length, developed for uncooled infrared sensors using 8μm — 12μm infrared signatures. This lens assembly is a new addition to the already existing thermal imaging assemblies: f/#1.1 with 19 mm focal length and f/#1.3 with 14.9mm focal length. The opto-mechanical design, combined with the unique material properties of LightPath’s Black Diamond glasses, provide athermalization for temperature stability from -40°C to 85°C without adding to the cost. The f/#1.3 lens with 14.9mm focal length gives a 60 degree field-of-view when paired with a 15mm sensor with a 25 micron pixel pitch.
