Griffin™ Linear 5-L Series

Midwave Infrared (MWIR), 5 µm Pixel Pitch Camera Core, Linear Cooler

The Griffin™ 5-L Series camera cores include the Griffin™ VGA5-L (640×512) and Griffin™ HD5-L (1280×1024), featuring the industry’s smallest MWIR sensors made to enable the smallest of cryocooled infrared imaging systems. The Griffin™ 5-L Series captures snapshot MWIR imagery using Attollo Engineering’s HOT Type-II Superlattice (T2SL) detector material. The extremely small pixel pitch of 5 µm enables more pixels on target with a short focal length optic, reducing overall sensor size. The Griffin™ 5-L series uses a linear cooler for short optical axis length and high power efficiency.

The Griffin™ VGA5-L and Griffin™ HD5-L sensors are also capable of supporting broadband imaging along with day and night laser see-spot capabilities. The Griffin™ 5-L series MWIR Cores are built for low SWaP applications and offers a significant opportunity for cost savings at the system level compared to competing MWIR cameras. With a volume of 169 cm³ and a weight of 340 grams, these linear cooled cameras are ideal for small gimbal integration as well as use in SWaP-constrained handheld and soldier-carried systems.
