Abstract
PURPOSE: To solve the hardness of watching the screen caused by the shading of the bias illumination by securing a specified angle to the vertical angles of each prism for the TV camera which forms the monochrome image on more than one pickup surface each via the object lens and the color-separation prism.
CONSTITUTION: The monochrome is formed on the pickup surface of plural units of pickup tube 5 via object lens 4 and color-separation prisms 11∼14 and then picked up. In such TV camera, prisms 11∼14 are distributed in sequence along the optical axis of lens 4 and from the side of lens 4, and prism 11 and 12 are set opposite to prism 13 and 14 via the air layer. And then the dichroic layer is formed between prism 12 and 13 as well as between prism 13 and 14. Then vertical angles θ1, θ2, θ3 and θ4 of prisms 11∼14 are set in the range of 5°≤θ1≤20°, 30.3°≤θ2≤35.8°, 31.5≤θ3≤34° and 15.2°≤θ4≤18.2° respectively.
