Offered here is an Olympus A 10x PL (positive low) phase contrast objective lens in excellent optical condition (the optics are free of fungus, scratches and internal dust). It was originally designed for the Olympus BH series of research grade microscopes but would work with any microscope with a tube length of 160mm. This is the much sought after 'positive low' phase contrast type for use with a phase contrast condenser, although it can also be used for brightfield illumination too.
