Q series: eyesafe laser rangefinder

 

The ZE1Q12 laser rangefinder is an ultra-small module that could easily integrate into various electro-optical systems. The system could be used in handheld binoculars, electro-optical platform, telecommunication, security and military applications. The module is especially suitable for soldier’s handheld laser rangefinders, small UAVs or drones.

Features:

  • lightweight design
  • Durable
  • Long range targeting
  • Multi targeting
  • Compact design
  • Eye-safe operation
  • Easy system integration

 

  • Handheld binoculars, handheld camera, handheld thermal camera for soldiers
  • electro-optical platforms for UAVs and vehicles
  • Optronic surveillance and reconnaissance
  • Fire control systems for land and sea targets
  • For determination of flight altitudes on airports
  • To measure the distance of ships from the coast
  • In observation outfits
  • In general, for applications of position determination
  • Applicable for mobile and mounted surveillance systems
