PRODUCT DESCRIPTON

The ERDI LASER LDR120K1 is a compact 1064 nm laser designator and rangefinder module designed for long-range target acquisition, precision ranging, and coded laser illumination. The system supports multiple designation modes, online coding, and high-energy output up to 120 mJ, making it suitable for UAVs, EO/IR pods, and fire control systems operating in harsh environments.


Key Advantage

  • Long-range performance: laser ranging up to 30 km on large targets

  • High precision: ranging accuracy ±1 m with ≥98% valid measurement rate

  • Flexible designation: supports short-cycle, long-cycle, and emergency illumination modes

  • Coded laser output: built-in fixed codes with online coding support

  • Rugged design: compact ≤2 kg and compliant with MIL-STD-810G
