HIKMICRO Gryphon GH35L product image


The GRYPHON GH35L is a thermal monocular made by HIKMICRO and is part of the Gryphon LRF series.


The Gryphon GH35L spots a crisp 35mm f/1 objective lens collecting thermal radiation. The default field of view on this thermal monocular is 7.5 by 5.7 degrees. It has a 8 times digital zoom to enlarge (parts of) the image. The eye relief distance is measured at 19.5mm.

Behind the lens of the Gryphon GH35L you can find the (uncooled, 12 micrometer) 384 x 288 pixels core refreshing the image at 50Hz. The thermal contrast (NETD) of this thermal monocular is <35mK and it's operating within the 8µm to 14µm infrared spectrum.

The physical dimensions of this thermal monocular read 87 x 73 x 167mm (lwh) and the scale reads 510 grams. This device is rated IP67. It handles dust, shocks, water (splashes) and submersion under water. It's rated for operating in temperatures between -30°C and 55°C.

The Gryphon GH35L can be used in scanning and surveillance, hunting adventures and police 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 525 meters 131 meters 65 meters
Person 1847 meters 461 meters 230 meters
Vehicle 4472 meters 1118 meters 559 meters

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