HIKMICRO Raptor RH50LN product image


The RAPTOR RH50LN is a thermal bi-ocular made by HIKMICRO and is part of the Raptor series.


The Raptor RH50LN spots a clear 50mm f/0.9 objective lens collecting thermal radiation. The default field of view on this thermal bi-ocular measures 5.3 by 4 degrees. It has a 16 times digital zoom to enlarge (parts of) the image. It has an eye relief distance of 15mm.

Behind the lens of the Raptor RH50LN you can find the (uncooled, 12 micrometer) 384 x 288 pixel microbolometer refreshing the image at 25Hz. The NETD of this thermal bi-ocular is <20mK.

The measurements of this thermal bi-ocular read 217.5 x 155 x 87.5mm (l/w/h) and the scale reads 1120 grams. This device is rated IP67. It's protected against dust, shocks, water (splashes) and submersion under water. It handles temperatures between -30°C and 55°C.

The Raptor RH50LN 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 750 meters 187 meters 93 meters
Person 2638 meters 659 meters 329 meters
Vehicle 6388 meters 1597 meters 798 meters

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