LR1500E4 Laser Ranging Module, 905nm Laser Distance Sensor for Night Vision, 1500m Long Range Laser Rangefinder Module

The ERDI LASER LR1500E4 Series Laser Ranging Module is a high-precision, compact rangefinder designed for demanding measurement applications. Operating at a 905 nm wavelength, it delivers a measurement range of 4–1500 m (up to 1800 m at nighttime) with a ranging accuracy of ±1 m for distances under 500 m. The module features a fast 2–10 Hz refresh rate, customizable up to 30 Hz, and achieves a measurement accuracy rate of ≥98% with a false alarm rate of ≤1%. Weighing just under 10 g and measuring approximately 1.01 × 0.56 × 1.03 inches, this ultra-compact module integrates seamlessly into handheld devices such as night vision equipment, thermal imagers, telescopes, and laser illuminators. It supports both single and continuous measurement modes and communicates via a UART-TTL interface at 115200 bps. Rated IP67 for dust and water resistance and IEC Class I laser safety compliant, it operates reliably from -4°F to +131°F. Ideal for border security, aviation, railway systems, law enforcement, and outdoor sports applications.

• LONG-RANGE PRECISION: Measures distances from 4 m to 1500 m (up to 1800 m at nighttime) with a ranging accuracy of ±1 m for targets under 500 m.
• HIGH-SPEED REFRESH RATE: Operates at 2–10 Hz adaptive measurement frequency, with higher refresh rates up to 30 Hz available in customized versions via serial interface.
• COMPACT & LIGHTWEIGHT DESIGN: Measures just 25.65 mm × 14.2 mm × 26.2 mm and weighs under 10 g, making it ideal for integration into handheld night vision devices, thermal imagers, and telescopes.
• RELIABLE COMMUNICATION INTERFACE: Features a UART-TTL interface at 115200 bps with dedicated test software and protocol documentation for convenient secondary development and integration.
• DURABLE & WEATHER-RESISTANT: Rated IP67 (inside lens cavity), operates from -20°C to +55°C, withstands 1000 g/ms shock, and carries an MTBF of 1500+ hours for long-term reliability.
