Microscopes Accessories. Aperture for Darkfield For Microscope.

A dark field system used with a vertical microscope and an adjustable aperature can be inserted. The light rays have to bounce before they get to the gemstone. It provides light entering the gem from the sides or obliquely against a black background which thus lets one see the inclusions more clearly than using transmitted light conditions (where the light path is directly through the stone from below). If you can set up a situation of lighting from the side (or all around) against a black background you can obtain dark field-like conditions. If you use a fiber optic light to light the gem ( Available on our M0143) from the side against a dark background then you can emulate dark field conditions.
