Here are the three bases for the PEAK microscopes. These are for the 2034 (acrylic), 2054 and 2054-EIM (aluminium) and 2054-CIL/2064-CIL) series with a higher cut-out for the coaxial illumination. Please check before ordering for which microscope you need the acrylic base as a spare part, as these parts are generally excluded from exchange.
