The HT-C8 75MM is a thermal monocular made by HTI and is part of the HT-C8 series.

Description

The HT-C8 75MM uses a quality 75mm f/1.1 lens to capture thermal radiation. The field of view (FOV) on this thermal monocular reads 5 x 3.7 degrees. It's equipped with a 4x digital zoom to capture additional details. The exit pupil diameter is 60mm.

Inside the housing of the HT-C8 75MM you'll find the (uncooled, 17µm) 384 by 288px thermal imaging sensor with a refresh rate of 50Hz. The NETD (Noise Equivalent Temperature Difference) of this thermal monocular is <40mK and it's operating between the 8µm and 14µm wavelengths.

The dimensions of this thermal monocular are 180 x 72 x 62mm (length/width/height) and weighs in at 500g. This device is rated IP66. It can withstand dust, shocks and water (splashes). Operating temperatures range between -20°C and 50°C.

The HT-C8 75MM is suitable for surveillance missions, hunting, law enforcement and 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 794 meters 198 meters 99 meters
Person 2794 meters 698 meters 349 meters
Vehicle 6764 meters 1691 meters 845 meters

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