80mJ Laser rangefinder and laser target designator 80K2 LDR80K2
Model: LDR80K2. The LDR80K2 uses common-aperture transmission and reception. LDA-pumped Nd:YAG and electro-optic Q-switching produce typical 1064-nanometer pulses. LDR80K2 pulse energy is 80 millijoules and divergence is 0.25 milliradian. Adaptive operation without temperature control enables immediate startup. It integrates into small airborne electro-optical pods, loitering munitions and other platforms for continuous ranging and periodic target illumination in semiactive laser guidance.
