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

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

Model: LRF0308C-01
The LRF0308C laser rangefinder module is a high-performance Class I eye-safe laser distance sensor designed for precise distance measurement across diverse applications. Operating at a wavelength of 1535±5 nm, it ensures reliable detection with a divergence angle of ~0.6 mrad and features an Φ8 mm launch lens paired with a Φ16 mm receiver lens for optimal signal capture. This Eye-safe 1535nm laser ranging module excels in long-range detection, capable of measuring distances up to ≥4600 m for large targets (4m×6m), ≥3200 m for NATO-standard objectives (2.3m×2.3m), and ≥1100 m for small drones (0.2m×0.3m). With a ranging accuracy of ±2 m and a high precision rate of ≥98%, the LRF0308C high-precision 1535nm laser module supports multi-target detection (up to 3 targets) at frequencies of 1–10 Hz. It operates efficiently within a DC 4.5–16 V range, consuming ≤2.5 W (average) and ≤7 W (peak). Compact (48mm×30.5mm×21 mm) and lightweight (≤32 g), it withstands harsh environments (-40 to +70 ℃) and interfaces via UART (TTL_3.3V), making it ideal for integration into Defense and Military, Surveying and Mapping, Aerospace and UAVs, autonomous systems, Scientific and Industrial Applications.

This compact and lightweight laser rangefinder module features a high-performance 1535nm microchip laser with 100μJ pulse energy, achieving a ranging distance of ≥3000m against NATO-standard targets. With dimensions of just ≤48×30.5×21 mm and weighing ≤32g, it’s ideal for integration into drones, optical pods, and portable surveillance systems.

Operating at 1–10Hz, the laser rangefinder module supports a TTL interface for easy control and data output. Its Class 1 eye-safe 1535nm wavelength ensures safety while maintaining high precision. Applications include military ranging, border monitoring, UAV/UAS systems, and more.

Designed for reliability and portability, this module delivers long-distance detection in an ultra-compact form factor—perfect for modern defense and security solutions.
