LENSES FOR USE WITH TELEVISION STUDIO CAMERAS
Four Kodak Ektanon lenses* of different focal lengths are supplied to
the television industry for use on television studio cameras of the image
orthicon type. These lenses were designed originally for use with
precision-built miniature cameras where excellent optical performance is a
requisite. Their focal lengths and high degree of correction also make
them ideally suited for use with television pickup cameras of the image
orthicon type where high optical quality is demanded. They
are capable of giving excellent resolution and sharpness and are
particularly well corrected for lateral and longitudinal chromatic
aberration. Inner air-glass surfaces are Lumenized to reduce reflections,
thereby improving shadow details and brilliancy in the image for both
black-and-while and color television work. Further technical details
concerning these lenses are given below.
