28 Laser Lines 638nm Red Multi Lines Laser Module for Crossroad Warning Laser Light

28 Laser Lines Red Multi Lines Laser Module for Crossroad Warning Laser Light BU-Laser designs this red multi-line laser module to enhance safety at busy crossroads for the Crossroad Warning Laser Light, serving as a high-visibility warning device, alerting drivers, pedestrians, and cyclists to potential hazards or traffic control zones. The Red Multi-Line Laser Module operating at a 638nm red wavelength—optimized for strong visibility in both daylight and low-light conditions—and featuring a multi-line design, it projects distinct, parallel laser beams across the intersection area, creating a clear visual boundary or warning zone.​ The Red Laser module’s multi-line configuration expands the warning coverage, ensuring the laser signals are visible from multiple angles and distances. This broad visibility is critical for crossroads, where vehicles and pedestrians approach from various directions, helping to prevent collisions during peak traffic, weather disruptions, or temporary road works. The bright red beams cut through fog, rain, or glare, maintaining consistent visibility to convey urgency and guide attention to cautionary areas.​ Core Specification: Wavelength 635nm-645nm Output Power 60mW for single laser line Working Voltage 3.3V Beam Mode Multi-lines beam, 28 laser lines Beam Size line width≤6mm @10m , 110 degree fan angle Housing Size 299*65*49mm (Customizable) Lens Optical Glass lens Lifespan > 10,000 hours Product Display: Our Services : We have over 15 years of experience with Lasers.
