Using a dissecting microscope

Lowmag DFTo set up a dissecting microscope for "dark field" viewing, the specimen should be placed over an opening so that light reflects only from surfaces between cover slip and slide, not from a surface beneath the slide. You may need to make a stand to hold the slide. The surface beneath the opening should be a flat black. Turn off any built-in illuminator. Aim a high-intensity light source toward the specimen at an angle, from the top or side through a glass dish or jar.
