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.
Claims14
An optical objective device to be moved linearly, including means for moving the device to a particular location over a prescribed length of travel, said means comprising:
- a fixed support relative to which linear movement of the device is desired;
- means including a piezoelectric motor fixed with respect to said support for initiating an accurate incremental linear movement;
- a first flexure fulcrum lever means having a first portion juxtaposed to and in contact with said piezomotor for receiving such incremental movement, said first lever means magnifying said linear movement;
- a second flexure fulcrum lever means having a first end in contact with a second portion of said first flexure fulcrum lever means for receiving said magnified linear movement, said second lever means further magnifying said linear movement;
- means for attaching said device to a second end of said second fulcrum lever means;
- and
- means for supporting said device linearly with respect to said fixed support.
An optical objective to be moved linearly including means for moving the objective to a particular location over a prescribed length of travel, said means comprising:
- a fixed support relative to which linear movement of the objective is desired;
- a piezoelectric motor operably connected to said support and a linearly incrementally movable piezo ram extending from said motor;
- a first lever positioned in a first plane and having a first end in contact with said piezo ram;
- a first flexure means connected to said first end of said lever for allowing to and fro flexure of said lever upon linear movement of said ram;
- a second lever extending in a second plane displaced from the plane of said first lever;
- means adjacent a second end of said first lever to contact a point on said second lever inward of a first end of said second lever;
- a second flexure means having a first portion connected to said first end of said second lever outward of said point and a second portion fixed with respect to said support;
- and
- means at a second end of said second lever for flexibly connecting said second end of said second lever to said objective.
