The ERDI LASER® 1535nm laser rangefinder modules are developed and manufactured based on ERDI’s proprietary 1535nm erbium glass lasers. They feature a compact design, flexible interfaces, and high beam quality, engineered for users requiring high-precision, long-range, eye-safe measurement.

Standard models include:

• Short-range Laser Rangefinder: 3–10 km (NATO targets)

• Long-range Laser Rangefinder: 12–18 km for 4 m × 6 m vehicle targets

Flagship product: the 3 km laser rangefinder module (LRF0305C / LRF0306C), developed from the MINI-100 laser, achieves precise 3 km measurement of NATO targets with an ultra-lightweight 14 ± 1 g design and 3 Hz / 10 Hz model options.

The ERDI LASER® 905nm semiconductor laser rangefinder module utilizes a 905nm laser diode as its core light source. It is a Class 1 eye-safe laser (IEC 60825-1) featuring high stability, precise measurement, compact design, and low power consumption.

Standard models include:

• Compact Laser Module: 1,000 m – 2 km

• High-frequency Laser Module: 20 m – 1,500 m
