1570nm Eye safe Laser Rangefinder Module 15km
PRODUCT DESCRIPTON
The LRF15E01ES 1570nm eye-safe laser rangefinder (diode-pumped OPO laser) is a high-tech product integrating optics, mechanics, and electronics. Its ranging capability is equal to or greater than 15km (under standard visibility, large target, reflectivity ≥20%) and is equal to or greater than 8km (under standard visibility, 2.3m*2.3m target, reflectivity ≥20%). This product features small size, light weight, high reliability, and long lifespan, enabling high-precision distance measurement of distant targets. It is widely used in various applications such as terrain mapping, geophysical exploration, mining, oil fields, ports, stations, airports, urban construction, roads, water conservancy projects, transmission line surveys, hunting observation, golf, outdoor activities, search and rescue, moving target tracking, speed measurement, vehicle automatic control, automotive safety alarms, industrial control, and more.
