The light source system is the core hardware for the flash measuring instrument to achieve accurate imaging and edge recognition, which directly determines the stability and accuracy of measurement data. High-end flash measuring instruments are equipped with an intelligent light source system combining four-zone annular light and backlight bottom light. The light source mode can be freely switched according to the material, color and light transmittance of workpieces to solve problems such as blurry imaging, unclear edges and light reflection interference of various workpieces.

The annular top light is mainly used for contour and surface dimension measurement of opaque workpieces, such as black plastic, metal hardware and dark stamping parts. It eliminates surface light reflection and shadows of workpieces through multi-angle light filling, clearly extracts the outer contour, hole and groove edges of workpieces, avoids stray light interference, and ensures the dimensional measurement accuracy of opaque workpieces.
Featuring high-contrast imaging, the parallel bottom backlight is suitable for transparent and translucent workpieces such as glass, acrylic, films and light-transmitting plastic parts. It can fully highlight the workpiece contour, filter light transmission interference, accurately measure the dimensions of thin walls and micro-pores, and solve the problem of blurry imaging and unrecognizable edges of light-transmitting workpieces.
The zoned adjustable light source can independently adjust brightness and angle. For workpieces with height differences and special-shaped concave-convex structures, it can accurately identify the dimensions of height edges, chamfers and steps, solve the problems of blurry edges and confused features of complex workpieces, and meet the high-precision detection requirements of various special-shaped and structurally complex workpieces.
Reasonable matching of light source modes can effectively avoid measurement errors caused by light reflection, light transmission and shadows, greatly improve the detection qualification rate and data stability of complex workpieces, and serve as the core configuration for flash measuring instruments to realize accurate measurement of all types of workpieces.
