Camera sensors and new machine vision applications tend to drive parallel advances in optics, and optics suppliers must continually evolve as machine vision technologies progress.

Although optical filters are often viewed as an afterthought in machine vision applications, their ability to optimize lighting and the entire vision system makes them so valuable that they should be considered from the initial planning stages of most applications.

Machine vision systems create images by analyzing the reflected light from an object, not by analyzing the object itself.

The lens is responsible for creating sufficient image quality to enable the vision system to extract the desired information about the object from the image.
