1570nm OPO Laser Rangefinder Module 50km
DESCRIPTION
The LRF50D120ES-02 is a 1570nm eye-safe laser rangefinder employing diode-pumped optical parametric oscillator (OPO) technology. It is a high-tech product that seamlessly integrates optical, mechanical, and electronic components. It features high resolution; under conditions better than standard visibility, its effective measurement range is ≥15 km for a 1 square meter flying target with reflectivity greater than 20%; and ≥50 km for large targets with the same reflectivity.
