摘要:
Adjustable pinhole, particularly for the illumination beam path and/or detection beam path of a laser scanning microscope, wherein the pinhole is defined by foil edges which are adjustable relative to one another, and at least two foils, each with at least one straight edge, are advantageously arranged relative to one another and/or connected to one another in such a way that their edges describe an L-shape and the L-shaped connection pieces are arranged on one another in such a way that they define a rhombic or square light passage and they are moved relative to one another for adjusting the pinhole.
摘要:
In an adjusting device for displacing individual elements (2) of optical systems or of measuring systems in which the element to be displaced is movable on a base (1) along a predetermined direction (x) by means of a piezoelectric actuator arrangement (21, 22) which is supported by the element (2) and which is constructed and controllable in such a way that it exerts shock pulses on the element (2) in order to carry out a stepwise movement of the element (2) on the base (1), the element (2) is arranged in a body (1; 27) which has an open or closed hollow cross section and is supported in a frictional engagement on this body, at least at one location, with the intermediary of a pretensioned spring device (8, 8′).
