5 Parts of a microscope Eyepiece – ocular lens, nearest the eye, magnifies the image 10x

6 Parts of a microscope Nosepiece – rotating part that holds the three objective lenses

7 Parts of a microscope Objective lenses – lens closest to the specimen, magnifies the image

8 Parts of a microscope High power – magnifies 40x
Medium power – magnifies 10x Low power – magnifies 4x

9 Parts of a microscope Stage – flat, table-like surface where the slide is placed

10 Parts of a microscope Stage clips – hold the slide on the stage

11 Parts of a microscope Diaphragm – disk-shaped device below the stage that controls the amount of light passing through the slide

12 Parts of a microscope Corse adjustment knob – roughly focuses the image by moving the stage up or down quickly

13 Parts of a microscope Fine adjustment knob – clarifies the image by moving the stage small distances slowly

14 Parts of a microscope Light source – the beam of light that passes through the slide

15 Use of the Microscope Page 947

16 Magnification The number of times an object’s apparent size is increased by the lenses

17 Total magnification Multiply the two magnifications together Eyepiece
