Optical Systems for Plumbicon Color Broadcast Cameras

In pickup devices for color TV the light has to be split into three components. This can be done quite satisfactorily by means of interference layers having a color selective reflecting action. There are various ways by which these layers can be incorporated in an optical system. Considerations that enter into the design of beam splitting systems are explained and an attractive new color-splitting device designed for Plumbicon color cameras is described. Because of its compactness the system can be combined directly with various types of zoom lenses avoiding all kinds of optical relay systems. Several phenomena, such as polarization effects, ghost images and flare, which can deteriorate the picture quality seriously, are greatly reduced.
