20km RS422 Port Long-distance Laser Rangefinder Sensor Modules
PRODUCT DESCRIPTON
Introducing the LRF20E01ES, a 1570nm eye-safe laser rangefinder that harnesses diode-pumped OPO technology, representing a state-of-the-art product that elegantly combines optics, mechanics, and electronics. This rangefinder is capable of achieving a ranging distance of ≥20km under standard visibility conditions when targeting large objects with a reflectivity of ≥20%, and ≥10km for a 2.3m×2.3m target with the same reflectivity threshold.
The LRF20E01ES is designed to be compact, lightweight, highly reliable, and boasts a long operational lifespan. These attributes enable it to perform high-precision distance measurements on remote targets, rendering it ideal for a broad spectrum of applications.
The versatility of the LRF20E01ES makes it an invaluable tool in numerous fields, including terrain mapping, geophysical exploration, mining operations, oil field surveys, port and station management, airport operations, urban construction projects, road development, water conservancy endeavors, transmission line inspections, hunting observations, golf activities, outdoor adventures, search and rescue missions, moving target tracking, speed measurements, vehicle automatic control systems, automotive safety alarms, industrial control processes, and a multitude of other scenarios.
