  • Viewing head
    Patent number: 4060835
    Abstract: The invention of this disclosure is a viewing head that packages a spherical mirror, beamsplitter, and cathode ray tube (CRT) in an enclosed container. The process of assembling the viewing head will automatically maintain the spherical mirror, beamsplitter, and CRT in optical alignment, making a time-consuming alignment procedure unnecessary. Because the optical equipment is contained within an enclosed container, the optical equipment will not have to be cleaned as often.
