TRANSMITTED LIGHT

     DARKFIELD TRANSMITTED LIGHT microscopes produce images in which the specimen appears light against a dark background.  This effect is achieved by placing a Darkfield "stop" in the filament plane of the condenser.  This "stop", often in the form of a slider or insert, is an opaque circle which keeps the light from being transmitted straight through the specimen to the eye.  Rather, only light coming around the stop is allowed to strike the object.  Because of the sharp angle of incidence, only the light which is scattered by the specimen reaches the eye.  At high magnifications a special oil immersion Darkfield condenser may have to be substituted for the normal Brightfield condenser.

     The microscope(s) below have been selected from our extensive inventory as examples of the type of instruments we sell.   Martin Microscope is not necessarily an authorized dealer for all products shown.  Price is listed for reference only and is subject to change without notice - please contact us for complete specifications, current price and availability.  The images to the right were actually taken through the microscopes pictured using a consumer digital camera and MM Series Adapter.
