In order to minimize the effects of magnetic fields in a color television camera, the color prism arrangement is constructed so that at least two camera tubes can be arranged parallel to each other.

Television camera equipped with a color-separating arrangement disposed

A precision adjusting system, comprising two components which can be adjusted with respect to each other, and at least two adjusting devices, each of which comprises a screw body which is mounted to be rotatable on the one component, a holder body which is rigidly mounted on the other component, and a plastically deformable torsion member which interconnects the two bodies. Rotation of the screw body causes a relative displacement of the two components, the torsion member then being twisted and plastically deformed and the two components being fixed in the adjusted position at the same time.

Precision adjusting device

A television camera in which a color splitting prism and a number of pick-up tubes are positioned, with respect to each other in a holder which comprises an annular seat for optical alignment of each pick-up tube, the relevant pick-up tube being pressed onto said seat, by way of an adapter ring connected thereto transversely of the tube axis, by means of a resilient pressure member which acts in the direction of the tube axis. The diameter of the parts of the seat and the adapter ring decreases in the pressing direction. The pick-up tubes fit in the holder in a locating manner and, after being pressed, do not exhibit play with respect to each other, so that variations of the position with respect to each other in reaction to shocks, and inherent picture registration errors, are avoided.

Television camera with pick-up tube mounting means

A deflection coil consisting of a number of elementary coils formed by folding flat coils along four folding lines such that at the area of the folding lines each turn crosses all other turns. Very accurate deflection coils can thus be manufactured in a simple manner.
