DESCRIPTION
Model LRF50D120ES is a 1570nm eye-safe laser rangefinder built around diode-pumped Optical Parametric Oscillator (OPO) technology.
This sophisticated optoelectronic device achieves tight integration of optical, mechanical and electronic assemblies.
It delivers superior ranging resolution. Under favourable standard visibility conditions, the effective detection range reaches no less than 15 km against a 1 m² aerial target with over 20% reflectivity. For large-size targets carrying identical reflectivity, the measurable distance extends to a minimum of 50 km.
