A portable television camera comprises a rigid housing accommodating the optical components, such as an entrance optical system, a color splitting optical system and the pick-up tubes which are arranged to bear on abutment faces which are strictly localized with respect to each other. The strict positioning of these components with respect to each other enables the use of pick-up tubes and an entrance optical system which are comparatively cheap, and combines low weight with good image quality. |
