LISQ Series
Four-sided illumination system with individually angle-adjustable bar lights
Features
By individually adjusting the angles of bar lights mounted on all four sides, the optimal illumination angle can be achieved according to the shape of the target, effectively reducing shadows and reflections caused by single-direction lighting.
High-contrast illumination formed from multiple directions enhances direction-sensitive micro defects such as scratches, dents, and edge defects, resulting in higher inspection reliability compared to single- or dual-direction lighting.
By adjusting both the illumination angles and placement, the system can accommodate flat, framed, and square-shaped targets, allowing the same illumination structure to be reused even when product specifications change.
Based on a mechanically fixed four-sided illumination structure with angle adjustment, the system minimizes setup variation between operators and enables consistent reproduction of identical inspection conditions.
Inspection Applications &
Example Images
- Graphic Inspection
- By applying four-sided illumination, uniform brightness is maintained regardless of printing direction, enabling stable detection of pattern distortion, breakage, and smearing.
- Surface Inspection
- By controlling the illumination angles from multiple directions to minimize reflections and shadows, fine surface defects such as scratches, dents, and foreign particles can be clearly highlighted.
- Shape Inspection
- Four-sided illumination simultaneously emphasizes the outer contours and edges of the target, allowing accurate detection of shape abnormalities such as dimensional deviation, deformation, and asymmetry.
- Close-Range Print Inspection
- By applying angle-controlled illumination even at close distances to suppress overexposure and reflections, fine text, lines, and micro-printing quality can be clearly evaluated.
