A standard colour monitor matching comparator

This paper surveys the problem of matching colour television monitors and the relative merits of optical or electronic aids. An optical design for assessing the normalizing white of a colour monitor is then discussed at length, and comments are made in detail on the alternative solutions at each stage of the design. It is concluded that a Lummer-Brodhun matching field, together with a tungsten lamp and glass filter combination for the reference D65, form an economical solution to the problem of a standard reference illuminant. Design flexibility allows the instrument to be used for other applications such as checking film review screens, and shadow mask tube phosphors.
