Pre-Engineered Telecentric Lenses: Don’t have a complete design? No problem!
Our Pre-Engineered lenses give our customers the option to choose from a variety of preliminary designs based on what suits their application best. Just tell us your application requirements (dimensions, wavelength range, field of view, etc.) and our team of expert engineers will optimize our preliminary designs to meet your exact needs. This will save you the hassle of fully designing a product from scratch and help reduce or eliminate design fees!
Telecentric lenses are specially designed to have the entrance and/or exit pupil at infinity distance. For telecentric lenses, all the chief rays are parallel to the optical axis in either image space or object space, or both. Telecentric lenses are used in imaging systems or projection systems to increase the measurement accuracy as compared to conventional lenses.
For an object space telecentric lens with the entrance pupil at infinity distance, the chief rays are parallel to the optical axis in the object space. Such lenses can be used in machine vision system for making the image magnification be independent of the object’s distance or position (within the depth of field) in the field of view.
For an image space telecentric lens with the exit pupil at infinity distance, the chief rays are parallel to the optical axis in the image space. Such lenses can be used in dimensioning systems for making the measurement accuracy be independent of the image sensor’s distance ( within the depth of focus) in the field of view.
For a double telecentric or bi-telecentric lens, the chief rays are parallel to the optical axis in both the object space and image space. With bi-telecentric lenses, the magnification in both image and object space is independent of distance or the position in the field of view. Such lenses can be used in a wide range of applications.
Shanghai Optics can quickly and cost effectively provide customers high performance telecentric lenses for use in a variety of applications including machine vision, inspection, metrology, image sensor test, projection system, etc.
