A parallel surface light source is a type of surface emitting light source that has better directionality. The LED is structurally optimized to be evenly distributed at the bottom of the light source, and after passing through a diffuse light guide plate, it forms a uniform illumination light on the surface. Special optical materials are configured on the surface to further optimize the emitted light. Usually used for detection of external contours.

Application scope:

Outline measurement

Measurement of machining dimensions

Glass bottle damage and foreign object detection

Detection of scratches, stains, or internal foreign objects, damages, etc. on the surface of transparent objects
