摘要： In a color separation prism system for a color television camera, a bias light source is located at a position substantially displaced from one or the other of the two intersections of (i) a plane including the optical axis of the taking lens of the camera and perpendicular to the plane including the optical axes of the three color light beams incident to the pick up tubes and (ii) the two parallel edges of a prism block formed by the entrance face thereof to which the light from the taking lens of the camera is incident and the upper and lower parallel faces of the prism block parallel to the plane including the optical axes of the three color light beams. The color separation prism system is particularly suitable for use in a system in which the refractive index of the glass constituting the prism blocks is as high as 1.7.

摘要： A zoom lens system of a color television camera is divided into a front lens component comprising a zooming lens system and a front part of a relay lens system, and three equivalent rear lens components each comprising a rear part of the relay lens system. A color separating prism system is located between the front and the rear parts of the relay lens system. The rear lens components are convergent so that the angle of light beams incident into the prism system may be smaller than that of the light beam incident into the image pick-up tubes.

摘要： A telescopic optical system composed of an objective, an eyepiece and an erect prism located between the objective and the eyepiece is provided with a reticle located on the focal plane of the objective. The objective, the eyepiece and the reticle are fixed to a casing of the telescopic optical system. The erect prism is capable of having its incident light optical axis and its emanating light optical axis aligned with each other and is rotatably mounted on the casing by means of gimbals provided with a rotor. The gimbals have two axes of rotation intersecting at right angle with each other and are located so that the two axes of the rotation are included in a plane which is perpendicular to the main optical axis of the telescopic optical system and passes through the middle point of the distance from the objective to the reticle.

摘要： An optical color-separation system for use in a color television camera having an image plane compensating lens associated with each of three camera tubes. Each compensating lens is provided with a diffusing area lying on the periphery thereof so as to be out of the image forming optical path. Photo-diodes are provided in opposing relation to the diffusing area. Light from the photo-diodes passes through the diffusion area to provide bias light for the camera tube.
