14 Jul 2008 Bilateral telecentric,Large depth of field,up to milimeters,
Constant magnification,Low Distortion The GCO-23 series of telecentric system is developed by using a pair of base lenses to achieve telecentricity required on object and imager plane. The combined telecentric lens systems is a focal lens system with an aperture stop located at the common focus of the front and back lens, resulting in the chief ray being parallel to the optical axis in both object and image space.Both the entrance and exit pupil are at infinity. |
