Overview
The Lumispot DLRF-C1.2-F is a 905nm laser rangefinder module engineered for compact, low-power, high-frequency distance measurement up to 1.2km. Using a semiconductor laser source rated Class 1 (<1mW) and Lumispot’s signal processing, it provides +/-0.5m accuracy and 0.1m resolution at 60-800Hz ranging frequency over a UART (TTL_3.3V) interface. With a 25*26*13mm footprint, 11g weight, and <=1.8W operating power consumption, the module integrates easily into portable, UAV, and embedded systems that require reliable and precise ranging.
