Lenses for Machine Vision Applications

Lenses project the captured light onto a camera’s sensor. Combined with a camera and lighting, they are instrumental in determining the image quality. In the worst case, choosing the wrong lens can result in an irretrievable loss in image quality.

When choosing the right lens, the balance between the required imaging performance - high resolution with optimal image quality - and price is critical. Ideal imaging performance saves processing time in the subsequent image analysis software and in many cases makes the analysis of even the finest structures possible in the first place. If a basic imaging performance and an average level of optical errors are acceptable, or if these errors can actually be corrected through image processing, then cost-efficient lenses are a better choice.
