ABSTRACT:
A fixture for use in adjusting a laser type leveling instrument has a cradle mounted on a base and operative to support the instrument with its normally vertical axis disposed horizontally. A pentaprism is mounted on a rotable platform on the base to reflect a laser beam, emitted by an instrument in the cradle and impinging on the pentaprism, in a horizontal path. The rotatable platform for the pentaprism permits movement of the pentaprism from a first position in which the beam is directed forwardly and a second position in which the beam is reversed and reflected rearwardly.
