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.
Collimated light with high collimation and small divergence. Provide the machine vision system with detailed, accurate and reliable image information, significantly improving inspection efficiency and accuracy.
For the electroplating circuits on the screen, they cannot be seen under normal conditions. By using point light with a coaxial teleconsteric mirror, the circuits can be clearly seen under high vertical illumination.
The contour inspection of the glue on the display screen. If the uniformity of a single light is poor, it cannot fully present the contour of the glue. By using a combination of dome and point light, the contour is obvious and the contrast is high.
Fiber optic light is widely used in the semiconductor industry, its high brightness, long life, low power consumption, greatly reducing the maintenance cost of products.
