The NLRF Series laser rangefinding telescopes are engineered around a proprietary 1535nm Erbium Glass Laser, achieving Class 1 eye-safe certification (IEC60825-1) for maximum operational safety. They deliver precise ranging from 20m out to 3.5km, 6km, or 10km with ±1m accuracy. Beyond distance, these versatile tools integrate angle measurement, altimeter, two-point ranging, target positioning, and ballistic calculation. With built-in GPS/BeiDou/GLONASS, Bluetooth 5.0 for mobile app interconnection, and OLED projection display, they are the ideal handheld or tripod-mounted solution for long-distance target acquisition and data collection in harsh environments (-40°C to +55°C, IP67).
