DESCRIPTION

The LDR40K1 Laser Ranging and Indication System is an advanced equipment specifically designed for high-precision target ranging and laser-coded indication. It not only achieves accurate long-distance measurements of ≥6000m but also has an effective range of ≥4000m for target indication. Renowned for its extreme lightweight design, the entire system weighs no more than 450g, making it compact and portable without compromising its stable and outstanding performance.

This system particularly offers customization services for the laser divergence angle, ranging from 0.3 to 1 mrad, flexibly meeting the needs of different operational scenarios. The LDR40K1 strictly adheres to internationally recognized standards, ensuring wide applicability and high reliability worldwide. With its exceptional durability, precise measurement capabilities, and compact, portable design, the LDR40K1 Laser Ranging and Indication System is undoubtedly the ideal choice for professionals pursuing efficient and accurate operations.

The laser ranging target indicator has the following functions:

  • It responds to laser target indication commands and can indicate laser targets using prescribed internal and external synchronization encoding methods.
  • If no stop command is received after initiating laser target indication, the indication will automatically stop after one cycle.
  • Laser coding setting function.
  • Laser ranging.
  • If no ranging command is received, and no stop command is received after initiating continuous ranging, ranging will automatically stop after 5 minutes (1Hz) / 1 minute (5Hz) / 20 seconds (20Hz). These durations can also be modified according to user requirements through communication.
  • Multi-target prompt function.
  • Power supply reverse polarity protection function.
  • Statistics on the number of laser pulse emissions.
