ABSTRACT:
An optical holder for use in optical equipment, such as an astronomical telescope. The optical holder includes a barrel which has an inner peripheral wall. At least one optical article having an outer peripheral surface, such as a lens or a mirror, is mounted within the barrel. The inner peripheral wall of the barrel and the outer peripheral surface of the optical article are so sized as to provide a gap therebetween. The structure further includes a spacer, or spacers, that fit in the gap to hold the optical article in place. An annular spacer may be used or a plurality of spacers may be fit between the inner wall of the barrel and the optical article in a circumferentially spaced relationship. A shifting screw may also be used to shift the optical article within the barrel.
