A device is provided with at least one parallelogram-shaped suspension mechanism built up with arms arranged along parallel planes and deformation joints interconnecting the arms and a setting device both of which are fastened to a table provided with a through hole and suitable for clamping the optical element to be set. Advantage of the setting device according to the invention is represented by the unvarying setting of the angular position of an optical element with a setting and resetting accuracy identical with or better than the wavelength of the light. Construction of the setting device is simple since its production does not require special technology. The setting device is applicable to advantage for optical measurement requiring high setting and resetting accuracy and unvarying setting, mainly in the case of lasers.
