  • Television camera comprising a rigid housing
    Patent number: 4057837
    Abstract: 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.
