HTI HT-C8 25MM

The HT-C8 25MM is a thermal monocular made by HTI and is part of the HT-C8 series.

Description

The HT-C8 25MM spots a clear 25mm f/1.1 objective lens collecting thermal radiation. The default field of view on this thermal monocular measures 14.9 by 11.2 degrees. It has a 4 times digital zoom to enlarge (parts of) the image. The exit pupil diameter measures 60mm.

Behind the lens of the HT-C8 25MM you can find the (uncooled, 17 micrometer) 384 x 288 pixel microbolometer refreshing the image at 50Hz. The NETD of this thermal monocular is <40mK and it's operating within the 8µm - 14µm infrared wavelengths.

The measurements of this thermal monocular read 180 x 72 x 62mm (l/w/h) and the scale reads 500 grams. This device is rated IP66. It's protected against dust, shocks and water (splashes). It handles temperatures between -20°C and 50°C.

The HT-C8 25MM can be utilized in surveillance, hunting trips, law enforcement (police, border patrol etc.) and SAR (Search and Rescue) 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
Rabbit 264 meters 66 meters 33 meters
Person 931 meters 232 meters 116 meters
Vehicle 2254 meters 563 meters 281 meters

Please note that these values are calculated, always consult the manufacturer for official range numbers.
