Laser indication (industrial/civil): Used as the indicator light source for laser levels and laser rangefinders. The 638nm red light has high visibility, and the 120mW power enables long-distance indication, suitable for construction and decoration scenarios.
Barcode/QR code scanning: As the light source for barcode scanning equipment, the 120mW red light can quickly excite barcode reflection signals, suitable for supermarket checkout and logistics sorting equipment.
Low-light imaging (industrial inspection): Used for detecting scratches and defects on metal surfaces. The 120mW red light can enhance the contrast between defects and the substrate, suitable for automated inspection lines.
