Darkfield Illumination

Darkfield observation in stereomicroscopy requires a specialized stand containing a reflection mirror and light-shielding plate to direct an inverted hollow cone of illumination towards the specimen at oblique angles. The principal elements of darkfield illumination are the same for both stereomicroscopes and more conventional compound microscopes, which often are equipped with complex multi-lens condenser systems or condensers having specialized internal mirrors containing reflecting surfaces oriented at specific geometries.
