Optical Metrology Basics: Telecentric Lenses

Put in Perspective

Conventional lenses for industrial image processing are "entocentric" with image formation in central projection. This perspective often is quite a nuisance for metrology. Telecentric lenses are designed for parallel projection and thus eliminate the warping produced by central projection. This article explains the concept of telecentric imaging.
