A universal microscope manipulator

a modified and improved model of a mechanical manipulator for observation of pinned and mounted insects is described. this device allows movement of the observed object around three perpendicular axes in the field of vision at all magnifications of stereomicroscopes. the main improvement of this new model is positioning of the guiding knobs for rotating around two of the axes next to each other, allowing faster and easier manipulation of the studied object. thus, one of the main advantages of this device is the possibility to rotate the specimen without the need to refocus. the device enables easily reaching a precession deviation in the intersection point of axes up to 0.5 mm in the process of assembling.
