LILS Series
Illumination that uses a focusing lens and high-brightness LEDs to concentrate light without diffusion, delivering high light intensity to a narrow area.
Inspection Applications &
Example Images
Uniform line-shaped illumination enables continuous imaging of moving objects, allowing stable inspection without image distortion even on high-speed transfer lines.
Uniform illumination along the line length makes it possible to efficiently perform 100% inspection of wide and long materials such as films, sheets, and web materials.
Based on high illuminance and uniformity, fine defects such as scratches, pinholes, contamination, and stains can be detected with consistent contrast across the entire moving direction.
When combined with a line-scan camera, resolution degradation along the moving direction is eliminated, maintaining fixed resolution and enabling precise inspection of patterns and repetitive defects.
Features
- Optimized for Line-Scan Cameras
- Line-shaped uniform illumination matches the imaging characteristics of line-scan cameras, enabling stable image acquisition of moving objects without distortion.
- Glass Surface Inspection
- Uniform illumination across the glass surface allows stable contrast-based detection of fine defects such as scratches, stains, and foreign particles along the moving direction.
- Display Quality Inspection
- Uniform brightness distribution over wide-area panels enables continuous inspection of brightness non-uniformity and line defects, making it suitable for display manufacturing processes.
- Suitable for High-Speed Measurement
- High-intensity and high-uniformity illumination ensures sufficient signal acquisition even at short exposure times, enabling precise measurement on high-speed production lines.
