1535nm Long Distance Laser Ranging Sensor Eye safe Laser Rangefinder Module 18KM

1535nm Long Distance Laser Ranging Sensor Eye safe Laser Rangefinder Module 18KM

Model: 1830c-01
The LRF1830C laser rangefinder module is a high-performance laser distance sensor designed for long-range, accurate measurements across various applications. Operating at a 1535nm wavelength with Class I laser safety, this long-range 1535nm LIDAR module offers precise ranging capabilities, supporting distances up to 23,000 meters for large targets, 18,000 meters for vehicle targets, and over 4,500 meters for people. The high-precision 1535nm laser module features excellent ranging accuracy (±1m), high precision (≥98%), and a low false alarm rate (≤1%). This compact 1535nm rangefinder module operates effectively in extreme temperatures ranging from -40°C to +70°C and offers low power consumption. Additionally, it supports multi-target detection (up to 3 targets) and provides reliable performance in industries such as defense, aerospace, and drone systems. This long distance laser ranging module also ideal for Handheld devices, Unmanned aerial vehicle, Electron-optical pod, and Border surveillance.

LRF1830C Long-Range Laser Rangefinder Module

The LRF1830C laser rangefinder module is a high-performance distance measuring device using 1535nm eye-safe glass laser and single-pulse TOF (Time of Flight) technology. It offers a measuring range up to 18km for 4m × 6m targets, making it ideal for surveillance, mapping, and defense applications.

Key features include single and continuous ranging, three-target detection, built-in diagnostics (APD temperature, voltage, blind zone), and a standby wake-up function. The module integrates a laser, transmit/receive optics, and control board in a compact design. With an RS422 interface, it supports easy integration and secondary development.

Reliable, powerful, and precise, the LRF1830C laser rangefinder module is perfect for long-distance measurement needs.
