TC5M series telecentric lenses are available in working distances of 110, 130, and 150 mm. Designed for 2/3-in. CCD sensors with a 5-Mpixel resolution, the lenses are suited for inspection and measuring tasks with varying distances to the camera where conventional lenses would provide different results depending on the distance. The TC5M series provides low distortion along with high resolution, providing new opportunities for use in metrology applications.

NEW PRODUCT PRESS RELEASE
Introducing 5 megapixel models:
Telecentric lenses for extremely high resolution applications
Karlsruhe – Lensation's TC5M series consists of telecentric lenses for tasks with high requirements on precision. Designed for 2/3" CCD sensors with a 5 megapixel resolution, the lenses are available as various models for large work-ing distances of 110, 130 and 150 mm. They are especially suited for inspection and measuring tasks with varying distances to the camera where conventional lenses would provide different results depending on the distance.
Telecentric lenses enable users to greatly improve the measuring accuracy. On the object side and/or on the image side, they create an optical path parallel to the optical axis. Object-space telecentric lenses are used to detect objects with-out any perspective distortion. This requires a front lens that is at least as big as the object to be measured. Moreover, the magnification does not change when the object is moved on the optical axis. Therefore, the resulting image will al-ways be the same size regardless of the distance to the object. It will, however, be out of focus when the object is moved outside of the ideal object plane. Measurement lenses use this characteristic to allow for a certain tolerance re-garding the distance and position of the parts to be measured. The TC5M series provides extremely low distortion along with a very high resolution, thereby opening up new possibilities for users in metrology applications.
Founded in 2006, Lensation GmbH specializes in the manufacturing, distribution and design of industrial lenses. The Karlsruhe-based company provides a wide range of lenses, focusing on particularly demanding applications. Lensation procures image processing components with specifi-cations according to customer requests, drawing on close contacts with suppliers from Asia. If a desired product is not available, Lensation also provides development services including exclusive custom-tailored OEM models and contract manufacturing according to customer designs. The service range also includes free-of-charge consultation on the topics of lenses, lighting, optical components and intelligent cameras.
