Imaged plates for positioning system calibration
Typicaly chrome on glass patterns for reflective or transmitted light, with high contrast images.
Typical products can be chessboard patterns, dot arrays or multiple repeat patterns which are used to set-up or calibrate positioning systems. The accuracy and definition of these patterns needs to be to a very high standard, typically 3x better than the specification of the equipment on which it is used. The glass plates themselves are often made to custom designs and can vary in size and shape to suit the application.
Graticules has standard grid plates, chessboard patterns and a dot array in their standard product portfolio.
