Glass surface, Painted surface defect detection
Glass surface, Painted surface defect detection
Customer requirements

Due to the reflection of the glass surface and mirror, ordinary industrial lenses can not detect all defects, and the light and shade of the picture taken is inconsistent.

Advantages of the Plan

The lens adopts special optical and structural design, which minimizes the stray light problem of ordinary internal coaxial lighting lens and improves the uniformity of lighting. Various scratches and oil stains on the surface can be clearly presented. In the project of shooting large field of view, the image uniformity is more than 99%.
