ABSTRACT:
A method for making an airtight and highly precise fitting for a spherical lens in a cylindrical opening within a metallic body. The spherical lens is axially pressed into the opening where the diameter of the opening is smaller than the diameter of the spherical lens. The diameter of the cylindrical opening is designed so that the spherical lens plastically deforms the metallic body when it is inserted into the opening.
