CNGE-LRF-4 Laser Rangefinder Module
The CNGE- LRF -4 eye-safe laser-ranging module is based on CNGE’s independently developed 1535nm erbium-glass laser and is a Class 1 eye-safe product. It uses single-pulse ranging, with a maximum range ≥4000m. Selectable UART (ttl3.3 v) and RS422 electrical interfaces are provided, along with host testing software, a command set and a communication protocol for secondary development. It is compact, lightweight, stable, highly shock-resistant and domestically produced.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
