At this stage, the external dimensions of notebook computers and mobile phone casings are getting more and more attention, and the requirements are becoming more and more strict.

At this stage, the measurement is no longer limited to manual or caliper measurement, but requires fast and accurate mass inspection. Most of the dimensions of computer and mobile phone casings are the size of the upper surface, which requires multi-angle and multi-directional illumination of the light.

Easson's up light source 5 rings and 8 zones 40 directions of illumination, through different angles combination, enhance the image contrast of the measurement site , while reducing stray light interference, easily obtain high-contrast pictures, making software edge-finding processing efficient and reliable, and ensuring detection repeatability.
