LW Scientific® I4P-CND7-DFOL is the oil darkfield condenser for the I4™ microscopes. Darkfield microscopy employs refracted light to illuminate live, unstained specimens with a bright contrast against a dark background. By obstructing the center of the brightfield light and preventing direct rays from entering the objective, only the outer oblique rays reach the specimen.

To achieve the sharpest darkfield imaging, which is much clearer than with any dry darkfield condenser, place two drops of immersion oil on top of the oil condenser and raise it until the oil contacts the underside of the slide. Note that darkfield will not function with a standard 100x objective due to its high numerical aperture, but the optional 100x darkfield objective includes a built-in iris for convenient darkfield viewing
