6 Eyepiece – contains magnifying lens Arm – supports the body tube Stage – supports the slide being observed Body Tube – Maintains the proper distance between the eyepiece and the objectives Focus- Fine and course adjustments move the body tube to focus the image Objective – Provides magnification. Total magnification = eyepiece times objective Condenser or diaphragm – controls the amount of light passing up to the eyepiece Mirror or illuminator – produces or reflects light up toward the eyepiece
