Introduction
CNGE-LRF-4 eye safety laser ranging module is developed based on 1535nm erbium glass laser independently developed by CNGE. It is a class I product for human eye safety. The product is single pulse ranging, with the maximum range≥4000m, can choose UART (TTL_3.3v) and RS422 electrical interface, and provides upper computer test software, instruction set and communication protocol to facilitate the secondary development of users. The product has the characteristics of small volume, light weight, stable performance, high impact resistance, national production and so on.
