OGP Innovation Timeline

1945-1979

1945OGP and Eastman Kodak introduce the telecentric relay lens principle. Still regarded as the optical system of choice for high precision optical systems, it provides a constant working clearance and erect images.
1956Projectron™, the world's first electronic edge detection system for optical comparators, is introduced. Using photocell technology and analog circuitry, Projectron foreshadows the need for automation in the inspection industry.
1962The AG Electronic Smoothness Evaluator verifies the wash-and-wear properties of cloth. Certification with this system was required for textile manufacturers to use the "Sanforized" label.
1966OGP/Ex-Cell-O introduces the first practical high intensity arc lamps, making optical inspection at high magnifications possible for the first time.
1967The world's first video inspection system, the AG Model 875, debuts. Truly a harbinger of things to come, the Model 875 clearly demonstrates the capabilities latent in this technology.
1972OGP introduces the OQ-30A side screen Contour Projector with revolutionary granite surface plate foundation.
1975Automation takes another step forward with the introduction of CLIP (Closed Loop Incremental Positioner.) Automated positioning of comparator worktables can now be accomplished without the need for external controllers.
1977OGP patents the mercury arc surface illuminator with its unique paraboloidal reflector. This outstanding innovation enables high magnification inspection of surface details for the first time.
1978OGP introduces CLIP-COMP, the first integrated automated measurement software available for optical comparators, using a programmable desktop calculator.
1979The world's first side table optical comparator, the OQ-20, debuts. Dubbed the "projector for the eighties," its innovative design quickly makes it an industry favorite.
