A telecentric lens is a special type of optical lens (often an objective lens or a camera lens) that has its entrance or exit pupil, or both, at infinity.

Telecentric lenses are designed to have a constant magnification regardless of the object's distance or location in the field of view. This attribute is ideal for many machine vision …

Telecentric lenses eliminate the parallax error characteristic of conventional lenses by having a constant, non-angular FOV; at any distance from the lens, a telecentric lens will always have …

With telecentric lenses the image size is left unchanged with object displacement, provided the object stays within a certain range often referred to as “depth of field” or “telecentric range”.

Dec 10, 2024 · Telecentric lenses are specialized optical lenses that can set either their entrance or exit pupil to infinity. They are crucial in industrial use cases that require high levels of …

Telecentric lenses have entrance or exit pupils at infinity, providing orthographic perspectives for imaging and measurement.

Aug 15, 2025 · A telecentric lens is a type of machine vision lens that primarily corrects the parallax issue of traditional lenses. Its entrance or exit pupil is located at infinity, allowing light …

Unlike standard lenses, telecentric lenses are designed to maintain consistent magnification and eliminate perspective errors, making them essential for industries where precise measurement …

Bi-telecentric lenses are telecentric in both object and image space, which means that principal rays are parallel not only when entering but also when exiting the lens.

Dec 6, 2023 · Telecentric lenses are engineered with a specific optical design where the rays of light entering the lens are parallel to the optical axis in either the object space, the image …
