Abstract
A color pick up tube having a target structure comprising a transparent substrate a plurality of red, green and blue optical strip filters, each having a width F, mounted interleavely on one surface of the substrate, a thin glass layer, having a thickness T, mounted on the optical strips, a plurality of optically transparent, electrically conductive strips each having a width N, laid down on the thin glass layer such that each conductive strip corresponds to a respectively different optical strip. In order to prevent optical color cross talk, the widths F, N and the thickness T have the following relationship ##EQU1## WHERE .theta. IS THE INCIDENT ANGLE IN THE GLASS LAYER.
Claims3
A color pickup tube having a target structure comprising;
- a transparent substrate, a plurality of red, green and blue optical filter strips each having a width F and each mounted interleavely on one surface of the substrate, a thin glass layer having the thickness of T and being mounted on the optical filter strips, a plurality of optically transparent, electrically conductive strips each having width N and being laid down on the thin glass layer such that each conductive strip corresponds to a respectively different optical fiber filter strips;
- Characterized in that
- the widths F, N and the thickness T have the following relationship ##EQU4## where .theta. is the maximum incident angle of an optical beam to the conductive strips.
