Laser Rangefinder Module

DESCRIPTION

The LRF0816C eyesafe ranging module is developed based on our company's independently developed 1535nm erbuim-glass laser. It is classified as a level Ⅰ eye-safe product. The Laser Rangefinder Module utilizes monopulse ranging technology, allowing for a maximum range of up to 16km. It supports UART (TTL_3.3V) and RS422 interfaces, providing upper-level computer software with specified settings and communication protocols. Its advantages include stable operation, compact size, and lightweight design.
