PRODUCT DESCRIPTON
ERDI LASER LDR40K1 Laser Designator/Rangefinder is a compact, high-precision solid-state laser module for defense, low-altitude airspace security, and unmanned system integration. It provides accurate laser designation and rangefinding with internal or external synchronization, multi-target capability, and built-in protections for safe, reliable operation.
MAIN FUNCTIONS
The main functions of the LDR40K1 Laser Designator/Rangefinder are as follows:
- Responds to laser designation commands and performs laser illumination using specified internal and external synchronization encoding modes.
- If no stop command is received after illumination starts, the system automatically stops after completing one illumination cycle.
- Supports laser code configuration.
- Performs laser rangefinding.
- If no stop command is received after initiating continuous ranging, the system automatically stops after 5 minutes (1 Hz)or 1 minute (5 Hz).
- Provides multi-target indication capability.
- Includes reverse polarity protection for the power supply.
- Records and reports the total number of emitted laser pulses.
Key Advantage
-
Precise Ranging & Designation: ±2 m range accuracy and ±1 µs laser encoding precision.
-
High Stability: Pulse energy ≥40 mJ with ≤10% variation; measurement reliability ≥98%.
-
Flexible Operation: Single-shot, continuous (1 Hz / 5 Hz), and short/long-cycle laser designation.
-
Robust Environment: Operating temperature –40 °C to +60 °C; storage –45 °C to +70 °C.
-
Compact & Lightweight: Dimensions ≤115 × 65 × 60 mm, weight ≤460 g.
-
Safe & Reliable: Reverse polarity protection; average power ≤50 W, peak ≤100 W.
