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 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 the same FOV.

Aug 12, 2024 · 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 …

Nov 21, 2019 · Telecentric optics are lenses that provide the same magnification regardless of the object's distance or location in the field of view. The impression of spatial depth in the image appears …

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”.

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

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

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 precision in...

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 to enter the …

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.
