3V D9mm 635nm 5mW Red Grid Laser Module for Laser Scanning

The 3V D9mm 635nm 5mW Red Grid Laser Module—a miniaturized high-precision optical component exclusively optimized for laser scanning scenarios (portable contour scanning, flatness detection scanning, small part 3D scanning auxiliary, industrial vision scanning positioning). Highlighted by a D9 mm ultra-compact cylindrical package, 3V single low-voltage power supply, and a high-uniformity red grid laser output, this module features low power consumption, easy embedded integration, and stable Class 2 safe output. It delivers a clear, distortion-free grid laser surface array for laser scanning, realizing fast area positioning and high-precision contour sampling of scanned workpieces, and is perfectly adapted to the compact space and battery-powered characteristics of portable/handheld laser scanning equipment.

Core Advantages for Laser Scanning Application

1. D9mm Ultra-Compact Cylindrical Design: Ultimate Embedded Integration for Scanning Equipment

• Adopts standard D9mm cylindrical metal housing (length only 20mm for standard version), the mainstream miniaturized package for portable laser scanning equipment. The slim cylindrical structure fits the narrow internal routing/optical cavity of handheld scanners, pen-type scanning detectors, and small industrial vision scanners, without occupying extra space or affecting the equipment's lightweight design.

• Integrated all-in-one structural design: internal optical components (grating + focus lens) and laser diode are tightly fixed in the metal cylinder, with no external accessories, avoiding assembly errors during integration. The end face is a sealed optical window with anti-reflective coating, which is dustproof and scratch-resistant, adapting to the frequent movement and on-site use of scanning equipment.

2. 3V Single Low-Voltage Power Supply: Battery-Powered Scanning Equipment Exclusive Optimization

• Customized 3V DC single low-voltage drive (adaptable to 3.0–5V voltage fluctuation), perfectly matching the 18650/button cell/lithium polymer battery power supply system of portable/handheld laser scanning equipment, no need for additional voltage conversion module, reducing the internal circuit complexity of scanning equipment.

• Ultra-low power consumption: ≤0.2W at full power output (operating current only 30–40mA, typical 30mA), which effectively extends the battery life of wireless laser scanning equipment by 30% compared with 5V/12V modules, solving the pain point of short battery life of portable scanning devices.

3. 635nm 5mW Red Light: Balanced Visibility & Safety for Laser Scanning

• 635nm (±5nm tolerance) red light has high naked-eye visibility and low reflection interference on most material surfaces (metal, plastic, wood, ceramic, etc.), the grid laser can be clearly projected on the surface of scanned workpieces without overexposure on high-gloss surfaces or underexposure on dark matte surfaces, adapting to the diversified material scanning needs of laser scanning.

• 5mW Class 2 laser safe output (IEC 60825-1/FDA 21 CFR 1040.10), no risk of permanent eye damage for operators even with short-term direct view.
