1535 nm Laser Rangefinder Module Eye-safe Laser Distance Sensor 3000m

1535 nm Laser Rangefinder Module Eye-safe Laser Distance Sensor 3000m

Model: LRF0105C-01
The LRF0105C laser rangefinder module is a compact, high-performance 1535nm eye-safe laser distance sensor designed for precision distance measurement. This high-precision 1535nm laser module offers a maximum range of ≥4000m for large targets(4mX6m), ≥3000m for NATO-size(2.3mX2.3m) objects, and ≥1000m(0.2mX0.3m) for small drones. With a precision rate of over 98% and ±2m accuracy, it supports multiple ranging frequencies (1Hz to 10Hz) and can detect up to 3 targets simultaneously. This Compact 1535nm rangefinder module operates at a low power consumption of ≤0.8W, with standby below 1mW, and is suitable for harsh environments with an operating temperature of -40°C to +70°C. Its lightweight design (≈29g) and UART (TTL 3.3V) interface make it ideal for defense, UAVs, and aiming systems requiring long-range and reliable performance.

1535nm Eye-Safe Laser Rangefinder Module – Compact & Precise

This laser rangefinder module uses a self-developed bonded crystal erbium glass laser operating at 1535nm, making it a Class 1 eye-safe device. Designed for accuracy and efficiency, it can measure NATO-standard targets at distances of 3000 meters or more.

With its compact size and low power consumption, this laser rangefinder module is ideal for portable and embedded applications. It calculates distance using Time of Flight (TOF) technology by measuring the time it takes for a laser pulse to travel to the target and back.

Featuring a 3.3V TTL communication interface, it offers simple integration and stable performance. Perfect for use in military, industrial, and outdoor systems where precision and safety are critical.
