638nm 80mW Red Grid Laser Module for 3D Scanning

The PWM Adjustable 638nm 80mW Red Grid Laser Module—a precision-structured light source engineered exclusively for 3D scanning systems. Optimized with uniform grid projection, stepless PWM power control, and high beam stability, this module delivers clear, distortion-free grid patterns for rapid 3D reconstruction of objects, industrial parts, and human body surfaces, ensuring high-precision modeling and measurement.

Core Advantages for 3D Scanning

638nm Red Wavelength + Grid Beam Optimization: High-Precision Structured Light

• 638nm red light offers superior naked-eye visibility and low ambient light interference, making it ideal for indoor/outdoor 3D scanning scenarios. Compared to 650nm lasers, it exhibits 15% higher contrast on reflective surfaces (e.g., metal, plastic).
• Customizable grid pattern: Standard 10×10 grid with high line uniformity; no distortion or fading across the projection field (up to 1.5m×1.5m@2m distance). The grid acts as a high-density reference for 3D point cloud generation, enabling sub-0.1mm scanning accuracy.

PWM Stepless Power Adjustment: Adaptive to Diverse Surfaces

0–100% power tunability (80mW max output) via 1–10kHz PWM signal, compatible with mainstream 3D scanning controllers.

Dynamic power adjustment for surface adaptability:

Low power (10–30%): For high-reflective surfaces (metal, glass) to avoid overexposure and glare.

Medium power (40–60%): For matte surfaces (wood, fabric) to balance contrast and detail.

High power (70–100%): For dark surfaces (carbon fiber, black plastic) to ensure grid line clarity.

Fast PWM response time supports real-time power adjustment during dynamic scanning of irregular objects.
