T2SL Integrated Dewar Cooler Assembly 640x512 15μm Cooled Infrared Detector for Long Range Surveillance
Built upon Type‑II Superlattice technology and a linear cryocooler design, the C615H HOT cooled infrared detector delivers 640×512 resolution with 15 μm pixels. Operating its focal plane at 150 K, it maintains superior detection performance while achieving excellent SWaP characteristics: a lightweight 235 g form factor, stable 3 W power consumption, and a rapid 2.5‑minute cool‑down. Compact mechanical outlines support flexible integration, and an MTTF of ≥25,000 hours guarantees long service life. This detector meets market demands for dependable thermal imaging systems with low‑cost maintenance.

When discussing infrared thermal imaging, the first concept to consider is infrared radiation (IR). The wavelength of infrared radiation energy starts at about 700 nm and extends to about 1 mm. All objects emit a certain amount of heat in the form of infrared radiation, which is invisible to us because, across the entire electromagnetic spectrum, the naked eye can only see visible light.
The core component of infrared equipment is the infrared thermal detector, which can sensitively detect the tiny temperature differences of surrounding objects. It then collects this radiation information from the object and outputs temperature information for imaging based on those temperature differences. The hotter the object, the more infrared radiation it produces. If the intensity is high enough, you can feel it as heat.
