The L1 Movement is a compact, high-precision dual-emission laser ranging module for industrial and commercial use. It covers 0.05m~40m (front-end reference) with ±3mm±100×10⁻⁶×D accuracy (<30m) and ±5mm±100×10⁻⁶×D (30-40m), tested on Kodak whiteboard with <500lux illumination.
Offering red (650nm±20nm, 0.5-1.5mW) or green (0.5-4.5mW) laser (customizable), it’s ultra-compact (40×20.4×7.2mm) with low power consumption (<70mA standby, <200mA peak @3.3V). Complies with Class2 safety standards, operating at 0~40℃.
Ideal for small robotics, industrial automation (precision positioning/defect detection), smart home devices, and portable measuring tools. A space-saving, reliable choice for global buyers seeking mini laser ranging solutions.
