This page describes the use of lenses and filters to manage the properties of light within a system. Common applications could include machine vision, color sensing, or laser direction.
Lenses and filters manage the properties of light which passes through them. By selectively allowing light to pass through, filters can control color, light polarity and brightness. In this respect, a liquid-cristal display is simply a programmable filter.
Lenses are used to bend light into a new path.
