Optical Comparator Charts

OGP® optical comparator charts are produced from CAD-generated masters scribed on a high precision plotter for uniform line weight and accurate location. Replacement screens are made of glass, while overscreen charts are made of dimensionally stable plastic. Plastic charts are produced with our exclusive Permaline sealed image process. The chart lines are sealed into the plastic for unmatched durability and long life.

Precision screens and charts are specifically designed for OGP, Ex-Cell-O, Kodak, Bausch and Lomb, and Bendix comparators.
