Abstract
PURPOSE: To eliminate unsightly screen due to shading of bias illumination, by making the top angle of each prism in the TV camera having the color separation prism system into the value within specific range, and by providing air gap between prisms.
CONSTITUTION: Mono-color picture is formed and picked up on the pick up screen of a plurality of pick up tubes 5 with the objective lens 4 and the color separation prisms 11 to 14. The prisms 11 to 14 are sequentailly located along the light axis of the lens 5, air gap is placed among the prisms 11 to 13, and the diechroic layer 12" is formed between the prisms 12 and 13 and the diechroic layer 13" is formed between the prisms 13 and 14. Further, the top angles θ1 to θ4 of each prism are taken as the value within the following ranges. 5°≤θ1≤20°, 30°≤θ2≤35.8°, 31.5°≤θ3≤40°, 15°≤θ4≤18.2°.
