SUMMARY A simple illumination system is described that can be easily adapted to a laboratory stereomicroscope allowing for low power high contrast dark field surveying. The system uses commercially available fibre optic lamps, standard bright field objectives and produces a large, evenly illuminated field suitable for photography.
