A telecentric lens is a unique optical device with its entry or exit pupil, or both, set at infinity (often an objective lens or a camera lens).
No matter how far away or where in the field of view the object is, telecentric lenses are made to have a consistent magnification. Given that measurements of an object’s size will be location-independent, this feature is excellent for many machine vision measurement applications.
Finding the magnification under which the picture fits the sensor is the key to picking the ideal telecentric lens. For instance, you could need to use a telecentric lens and a 2048 x 2048, 5.5 m sensor to measure a geometrical characteristic of a mechanical item (a nut).
The Global Telecentric lenses market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
OPTO Telecentric Lenses 1/3″ TO 2/3″ Sensors
Any measuring system using machine vision must have bi-telecentric lenses for matrix detectors up to 2/3′′ in the TC series. These lenses can fully use high-resolution detectors like those with a resolution of 5 MP – 2/3′′, capturing pictures with excellent fidelity and precision.
These optics can achieve pure telecentricity thanks to Opto Engineering’s bi-telecentric design: there is no magnification change when moving away from or towards the subject, which makes the TC series perfect for measurement applications of mechanical parts, from small clock gears to extruded aluminium profiles.
No other lenses can provide the same optical performances in terms of telecentrity and absence of distortion; moreover, by combining our TC lenses with LTCLHP telecentric illuminators, you may further improve depth of field and optical precision.
