1570nm Long Distance, High Hrecision Eye safe Laser Rangefinder 40km
PRODUCT DESCRIPTON
The LRF50D80ES, a 1570nm eye-safe laser rangefinder utilizing diode-pumped OPO technology, is a high-tech product that seamlessly integrates optics, mechanics, and electronics. Under better-than-standard visibility conditions, it boasts an operating range of ≥12km for a 1m² flying target with reflectivity >20%, and ≥40km for large targets with the same reflectivity. This product is characterized by its small size, light weight, high reliability, and long lifespan, enabling high-precision distance measurement of distant targets. It finds wide application in various fields such as terrain mapping, geophysical exploration, mining, oil fields, ports, stations, airports, urban construction, road development, water conservancy projects, transmission line surveys, hunting observation, golf, outdoor activities, search and rescue operations, moving target tracking, speed measurement, vehicle automatic control, automotive safety alarms, industrial control, and more.
