Description
Telecentric lens, imager format 2/3″, FOV 89.7 x 67.3mm, DOF 100mm, working distance 284mm
An optical system where the entrance and/or exit pupil is imaged to infinity caused by locating the aperture stop at the front or back focal point of the system. Because of this, the principal rays are parallel to the optical axis in the image and/or object space. Thus, it yields a special form of perspective: telecentry (as opposed to the natural entocentric perspective). Through telecentric perspective, objects of the same lateral distance on both sides appear to be equal in size at various distances within specific limits (telecentric range) in an image.
