LightPath Technologies Introduces the 75mm F/1.0 LWIR Thermal Lens Assembly at SHOT SHOW 2021

ORLANDO, FL / ACCESSWIRE / January 19, 2021 / LightPath Technologies, Inc. (NASDAQ:LPTH)(“LightPath,” the “Company,” or “we”), a leading vertically integrated and integrator of proprietary optical and infrared components and high-level assemblies, today announced the expansion of its line of long wave infrared (LWIR 8-12um) thermal lens assemblies for thermal weapon sights, thermal monoculars and thermal binoculars. The 75mm F/1.0 LWIR TWS lens assembly’s part number is 7100406.

LightPath’s 75mm EFL lens features a large f/1.0 aperture for excellent light collection. This lens is optimized to be used with an uncooled microbolometer up to VGA resolution, producing an 8deg HFOV on a VGA-17µm detector, or a 6deg HFOV on a VGA-12µm detector. With near diffraction-limited MTF, <0.5% distortion and >97% relative illumination across the full field of view, this lens is ideal for applications requiring high image quality. LightPath offers both high efficiency anti-reflective (HEAR) and diamond-like carbon (DLC) coatings for the optimal balance of transmission and durability for rugged environments.

Product Description:

DRI for 17µm pixel detector (assumes 1.5m critical dimension)
• Detection (1.5 POT) = 4.4km range
• Recognition (6 POT) = 1.1km range
• Identification (12 POT) = 550m range

DRI for 12µm pixel detector (assumes 1.5m critical dimension)
• Detection (1.5 POT) = 6.25km range
• Recognition (6 POT) = 1.56km range
• Identification (12 POT) = 780m range
