Holds down the slide on the stage. 8  Eyepiece (Ocular Lens) and Body Tube Eyepiece The lens you look through that magnifies the specimen. Body Tube The hollow tube through which light passes. It holds the lenses a part. 9  Objective (Low Power/High Power Low Power Objective Magnifies the specimen at a lower power High Power Objective Magnifies the specimen at a Higher power 10  Diaphragm and Light Source Diaphragm Changes the amount of light reaching the objective lenses.
