French sensor maker Lynred is showing its first compact high-resolution  midwave (MWIR) ‘HOT’ (High Operating Temperature) infrared sensor that can detect individual at a distance of 14km.

The Seegnus HOT infrared sensor has an SXGA resolution of 1280 x 1024 with a small pixel pitch of 7.5µm for manufacturers of long-range/large Field-of-View (FoV) miniature infrared systems. This provides a net 20% increase in Detection/Reconnaissance/Identification (DRI) range performance over Lynred’s earlier VGA model.

Combined with the latest 220mm folded compact f/4 COTS optics, the Seegnus sensor can detect individuals at a distance of up to 14.5km in a 630m width imaged scene, while recognizing them at 3.9km in a 170m width imaged scene.

The low acoustic noise and low power consumption of under 3.5W for the infrared sensor allow lightweight, durable and stealthy packaging for long-range imaging in tactical gear. These include Unmanned Aerial Vehicle (UAV) gimbals, tactical goggles, armoured vehicle sights, Remote Control Weapon Sights (RCWS) and submarine optronic masts. Seegnus can also be used in fixed or airborne surveillance systems in any industry.

 “Seegnus incorporates all of the top infrared imaging performance criteria in demand from camera makers today: a compact large array format with 150K ‘HOT’ design, coupled with low weight and low power consumption advantages,” said Alain Manissadjian, product manager at Lynred.

“Seegnus extends Lynred’s SWaP (small Size, low Weight, low Power consumption) portfolio in the MWIR range and shows its robust capability in mastering III-V semiconductor technology.”

The PlugUp platform enables Lynred to maintain the same form factor and identical mechanical, optical and electrical interfaces across designs, making an SXGA upgrade from Lynred’s previous compact VGA model is extremely easy.

Lynred was formed from the merger of Sofradir and Ulis in 2019 and is developing a €85m production plant in Grenoble, France.
