Product Description

LR Series Low Angle Ring Light for Dark Field Machine Vision Inspection

The LR Series Low Angle Ring Light is specifically designed for machine vision applications requiring enhanced edge detection and surface texture analysis. With its low-angle LED illumination, it creates a dark field effect that emphasizes surface defects such as scratches, engravings, and fine irregularities.

Equipped with high-brightness LEDs mounted on a precision-engineered flexible circuit board, the LR Series delivers consistent and reliable lighting performance. Advanced wave-soldering technology ensures superior build quality and long-term stability in demanding industrial environments.

This lighting solution is ideal for inspecting reflective and glossy surfaces where traditional lighting fails to reveal subtle details

Key Features

  • Low-angle illumination for strong dark field effect
  • Enhanced edge detection and surface defect visibility
  • High-brightness LEDs for stable and uniform lighting
  • Flexible PCB design for precise light positioning
  • Advanced wave-soldering for improved durability and consistency

Applications

  • PCB and substrate positioning
  • Chip and electronic component inspection
  • LCD alignment and inspection
  • Plastic container and packaging inspection
  • Label inspection and verification
  • IC marking inspection
