No magnification variation! A lens ideal for measuring dimensions and positioning of objects with depth.
A "telecentric lens" is a lens that has an optical system where the principal rays are parallel and do not intersect the optical axis on the object side, the image side, or both. In an optical system where telecentricity is established, there is no angle of view, and even if the object or image moves up and down, there is no change in magnification. Because there is no change in magnification even when the focus is blurred, it is an ideal lens for measuring the dimensions and positioning of three-dimensional test objects. 【Features】 ■ When used in conjunction with coaxial reflected illumination of a telecentric optical system, it can capture subtle changes in the reflectivity of mirror-like objects. ■ It is optimal for distinguishing dirt, fingerprints, scratches, and ID marks on wafers and glass substrates.
