Universal mount for a specimen holder

摘要

A universal mount is disclosed herein for positioning small subjects for macro-photography which includes a box-like base 11 having a releasable fastener for detachably coupling with a tripod mount of a conventional camera so as to downwardly depend therefrom. A fixed barrel tube 15 outwardly projects in a cantilevered fashion from the side of the base and includes bearings for slidably and rotatably receiving an elongated focus tube arranged in coaxial and telescoping relationship therewith. A rod holder is carried on the free end of the focus tube having an axis normal to the central longitudinal axis of the focus tube for slidably supporting a specimen holder such as a clip or transparent box.
