ABSTRACT:
An adjusting means for a microscope objection (51a) or the like is provided comprising a fixed support (53), a piezomotor (52) having an output ram (54) capable of accurate incremental movement and which is adapted to strike a flexible leg or lever (55) which amplifies the incremental ram movement. The cantilevered end (57) of leg (55) moves arcuately to strike a second oppositely extending lever (60) which is journalled in a flexure pivot (61). Lever (60) extends back toward the objective (50a) and further accurately amplifies the incremental ram movement so as to move the objective a finite distance based on electrical inputs to the piezomotor.
