Applications of Telecentric Lenses

Telecentric lenses, as essential components in machine vision systems, offer exceptional optical properties and outstanding performance. Their unique capabilities make them indispensable in numerous high-precision and demanding industrial and technological fields.

Concept of Telecentric Lenses

Telecentric lenses are a type of optical system designed to correct the parallax effect seen in traditional lenses by placing their entrance or exit pupil at infinity. This design ensures that the magnification of the captured image remains constant over a range of object distances, eliminating the perspective distortion that typically results in objects appearing larger when closer to the lens. The core principle of telecentric lens imaging combines the concepts of traditional lenses and pinhole imaging.
