Description
Among the most essential components of today's advanced automated assembly equipment is machine vision. Machine vision is used for substrate recognition, component centering and inspection, and machine setup procedures. The primary task of machine vision is to distinguish features of interest from the background. This central task is made easier if the input image has a high degree of contrast. Of the individual parts that make up a machine's vision system, the lighting system has the most influence on image contrast.

This whitepaper addresses a flexible lighting module that helps manufacturers overcome the challenge of imaging a variety of substrates.
