The LM640 35MM is a thermal monocular made by LMIR.

Description

The LM640 35mm comes equipped with a clear 35mm f/1 lens to capture thermal signatures. The FOV on this thermal monocular measures 18 x 15 degrees. It comes with a 4x digital zoom to get additional details.

Inside the housing of the LM640 35mm you'll find the (uncooled, 17µm) 640 by 512 pixel thermal sensor with a refresh rate of 30Hz. The NETD of this thermal monocular is <40mK and it's operating between the 8µm - 14µm infrared wavelengths.

The measurements of this thermal monocular are 191 x 70 x 73mm (l/w/h) and weighs 490g. This device is rated IP67. It's protected against dust, shocks, water (splashes) and submersion under water. It handles temperatures between -40°C and 60°C.

The LM640 35mm is built for 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 370 meters 92 meters 46 meters
Person 1303 meters 325 meters 162 meters
Vehicle 3156 meters 789 meters 394 meters

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