1570nm Eye safe Laser Rangefinder Module 30km
PRODUCT DESCRIPTON
The LRF25A02ES, a 1570nm eye-safe laser rangefinder utilizing diode-pumped OPO technology, is a high-tech product that seamlessly integrates optics, mechanics, and electronics. Its ranging capabilities are as follows:
Under standard visibility conditions, for targets with a size of ≥0.05m² (such as the DJI Phantom 4 drone), the operating range is ≥5km.
Under standard visibility conditions, for large targets with a reflectivity of ≥20%, the operating range is ≥30km.
For a target of 2.3m x 2.3m with a reflectivity of ≥20%, the operating range is ≥15km under standard visibility conditions.
This product features a 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.
