News ARTICLE Grating Coaxial Line Scan Light Inspection Application Grating coaxial line scan light inspection application Principle Use new optical element with coaxial line scan light can be used for detection of bump on smooth surface. The light source is equipped with a grating element. When a bump is detected, the fringe image will be deformed, and the deformation position is the position of the bump. Features: High light transmittance, good uniformity. Designed with coaxial line scan light. Special optical design, good imaging effect. Applications: Smooth surface defect detection such as bumps, scratches, black spots, etc. Case example ■Reflective film surface, bump detection ■Mobile phone polarizing film surface, bump detection Note: For bump points on smooth surface, it is easy to find the defect location and enlarge the defect by judging the bend of the stripe. Line scan system has a large detection area, and a relatively large light source can be selected according to the size of samples to meet the FOV. The uniformity line scan light is better than that of area scan light.  ■Detection of defects such as slight scratches on polarizing film Note: For slight scratches on smooth surfaces, it is difficult to see the defects by conventional light. Use grating coaxial line scan light, the defective parts show grid clutter, highlighting the defects, which is conducive to machine vision recognition. 2025-07-04 15:01:33 << Previous Page Next Page>> ARTICLE Press HOT ARTICLE (LuxMV)AOI Applications Light L LuxMV SWIR Light Applications New Product For Concave-Convex Condenser Lens For Mounting On 4 Generation High Uniformity L x ABOUT US LuxMV (Lighting & Tech Specialist) is a leading organization in developing and manufacturing machine vision lights for the advanced lighting industry.
