1570nm OPO Laser Rangefinder Module 30km LRF25A02ES
DESCRIPTION
The LRF25A02ES is a 1570nm eye-safe laser rangefinder built around diode-pumped OPO technology. This compact optoelectronic unit delivers seamless integration of optical, mechanical and electronic subsystems.
Under standard visibility circumstances, it achieves an effective ranging distance of no less than 5 km for targets with a surface area of 0.05 m² or larger.
