An earlier article in Microscopy Today, "Rediscovery of Darkfield Dispersion Staining while Building a Universal Student Microscope," noted that the darkfield inserts were made for Peter Cooke (MICA, Chicago, IL) to be used to teach high resolution dispersion staining in his advanced microscopy classes using Olympus BH2 microscopes and the Olympus 1.25 NA Abbe condenser. Peter has asked whether there is a better condenser design that will reduce the time and effort needed to switch between brightfield and darkfield.
