    摘要: In a television camera having a color resolving prism system for forming monochromatic images on the image pickup surfaces of a plurality of image pickup devices by an objective lens the color resolving prism system has first, second, third and fourth prisms as is named in the order from a side of the objective lens along the optic axis of the objective lens, the first and second prisms, with their refracting angles opening in opposite directions, are edisposed with an air layer interposed therebetween or are joined together with a dichroic layer interposed therebetween, the second and third prisms are disposed with an air layer interposed therebetween, the third and fourth prisms are joined together with a second dichroic layer interposed therebetween, and the values of the refracting angles of the first .theta..sub.10 or .theta..sub.21), second .theta..sub.10 +.theta..sub.11 or .theta..sub.22, third .theta..sub.23 and fourth .theta..sub.24 prisms satisfy the following conditions:(1) in the case where the first and second prisms are disposed with the air layer interposed therebetween,5.2.degree.

    摘要: A television camera is provided with a color resolving optical system for color resolution and for forming a plurality of optical paths, the color resolving optical system having at least one dichroic film, a plurality of image pick-up tubes disposed on the optical paths for receiving the image of an object to be photographed, and an illuminating device emitting a plurality of illuminating lights of a predetermined wavelength range and provided with an adjuster for adjusting the quantity of light of at least one of said illuminating lights. The wavelength band width of said illuminating lights is narrower than the wavelength band width color-resolved by the color resolving optical system and/or the positions at which said illuminating lights are emitted differ from one another, whereby color shading of the image pick-up tubes is eliminated.
