The RangePRO Model L20LC is an OEM laser rangefinder module providing an advanced digital rangefinding capability for military, paramilitary and commercial applications. It integrates with host systems such as weapon, sensing, or surveillance and tracking stations, and thermal imaging cameras. It requires power and control command input, and provides range-to-target and self diagnostic data output.

  • OEM module for integration into sensing, surveillance, tracking & weapons stations, and thermal imaging cameras & gimbals;
  • For land, sea or airborne applications;
  • Designed to withstand vibration, shock, and extended temperature operation, EM shielded.

  • InGaAs with time variant gain
  • Signals from the detector are digitally sampled and examined to determine all potential real target returns. An adaptive range threshold compensates for changing noise levels, maximising system capability under varying conditions.
