Detection of Dirt on the Surface of Mobile Logo
Customer requirements

Due to the serious reflection phenomenon on the surface of the logo, when using ordinary industrial lenses and coaxial light sources, surface defects can not be fully detected.

Advantages of the Plan

Through special optical design, the high-performance internal coaxial lens realizes the result that the light of the camera image and the light source can be emitted in parallel. It can clearly present the subtle scratches and dirt on the surface of the logo, which is convenient for visual software to recognize and process.
