telecentric

telecentric 

Pertains to an optical system in which its aperture stop is positioned so that the entrance pupil falls in the first focal plane, the exit pupil is at infinity, and the rays through the centre of the entrance pupil from all points on the object are parallel to the axis in the image space. Similarly, if the exit pupil lies in the second focal plane the entrance pupil will be at infinity, and the rays through the centre of the exit pupil will be parallel to the axis in the object space.

Using a high-speed, five-megapixel camera and telecentric measuring lens to provide high-resolution images (seven micrometers for small balloons at 40x and 28 micrometers for large balloons at 10x), this technology enables quick identification and classification of visual defects such as gel spots, fish eyes, crow's feet/strain lines, zipper lines, and embedded foreign particulates, as well as provides highly precise, repeatable dimensional measurements, using non-contact, high-resolution camera technology.
