Medium-Wave Infrared (MWIR) Cooled Thermal

Silent Sentinel offer long range cooled thermal cameras with lens options up to 960mm. Our mid-wave infrared (MWIR) cameras use highly sensitive InSb cooled MWIR FPAs, featuring a 15μm pixel size and 640px x 512px resolution. 

Medium-wave infrared thermal cameras, also known as Cooled Thermal cameras, can detect small targets at extreme ranges making them highly suited for long range applications in challenging weather conditions.

Medium-wave infrared (MWIR) is a subdivision of the IR band of the electromagnetic spectrum, which captures infrared energy in the 3 to 5 micrometer medium-wave infrared (LWIR) spectrum.

Benefits of cooled thermal:

– Very sensitive to temperature change
– Great for longer range applications
– High resolution images

Medium-wave Infrared (MWIR) thermal lens options:

– 19mm to 275mm
– 15mm to 300mm
– 35mm to 690mm
– 45mm to 900mm
– 80mm to 960mm
