40mJ Laser rangefinder and laser target designator 40K1 LDR40K1
Model: LDR40K1. The LDR40K1 provides precision target ranging and coded laser designation, following international standards for compatibility and reliability. LDR40K1 weighs only 450 grams, ranges to ≥6000 meters and designates to ≥4000 meters in a compact, adaptable design. The LDR40K1 supports custom divergence from 0.3 to 1 microradian. LDR40K1 functions include: 1) Responding to designation commands using specified internal or external synchronized coding. 2) Automatically stopping after one cycle if no stop command follows designation startup. 3) Laser-code setting. 4) Ranging. 5) Automatically stopping continuous ranging without further commands after 5 minutes at 1Hz, 1 minute at 5Hz or 20 seconds at 20Hz; durations can be modified through communication. 6) Multitarget indication. 7) Reverse-polarity protection. 8) Pulse-emission counting.
