The CORSAIR is a thermal monocular made by IR&D.


The Corsair contains a crisp 60mm f/1 objective lens focusing the available thermal radiation. The field of view on this thermal monocular is 10.4 by 7.8 degrees. It features a 24 times digital zoom to enlarge your subject. The eye relief distance is measured at 30mm.

Behind the lens of the Corsair you can find the (uncooled, 17 micrometer) 640 x 480 pixels thermal core refreshing the image at 60Hz. The thermal contrast (NETD) of this thermal monocular is <50mK and it's operating within the 7.5µm to 13.5µm infrared spectrum.

The physical dimensions of this thermal monocular read 205 x 112 x 71mm (lwh) weighing in at 492 grams. This device is rated IP66. It handles dust, shocks and water (splashes). It's rated for operating in temperatures between -40°C and 65°C.

The Corsair is built to be used in scanning and surveillance, hunting adventures, police operations, search and rescue, military missions and firefighting operations.

DRI Ranges

DRI stands for Detection, Recognition and Identification and is based on the widely used Johnson's criteria.

  • Detection Detect if an object is present
  • Recognition See what type of object it is (i.e. person, vehicle, airplane)
  • Identification For example see if someone is a friend or foe
Detection Recognition Identification
