Abstract: A target assembly of an image pick-up tube is provided which includes a stepped annular support member for a target substrate secured between a face plate and a front end portion of a tubular envelope of the image pick-up tube. The target substrate is affixed within the outwardly offset portion of the support member. The support member enables a fabrication sequence to be used which obviates exposure of the target substrate to mechanical or thermal shock during manufacture, permits the affixing material to be out of the field of view in a straightsides image pick-up tube, and furnishes automatically accurate centering of the target substrate. In combination with a softmetal sealing ring having an annular width extending from the inwardly offset portion of the support member to the inner side of a signal ring capping the face plate and the envelope, the support member also insulates the target substrate from mechanical shock during use of the image pick-up tube.
