Ocular/eyepiece : 2 eyepieces 10x magnification move in or out to adjust positioned correct=single circle of light Body : Holds mirrors that bend light into oculars images reversed and inverted Nose piece : Where objectives are attached Objectives : Contain magnifying lenses 4x, 10x, 40x, 100x Arm 2 | P a g e : Supports nose piece Holds power switch Holds focus adjustment knobs Stage : Flat platform that holds mechanical stage Mechanical Stage : holds slide moves slide to position it on stage Stage Adjustment Knobs : moves mechanical stage 2 knobs-right and left, forward and back Light Intensity Control : increases or decreases light output Substage condenser : 2 or more lens focus light passing through specimen improves sharpness 3 | P a g e Aperture diaphragm control : controls amount of light entering condenser 1/2 open for 10x and 40x completely open-oil immersion too much light bleaches out specimen Field diaphragm lever : increase or decrease light from light source remains open Light source : Halogen bulb Base : holds illuminator supports the rest of the microscope Fine focus adjustment : brings image into sharp focus raises and lowers stage in small increments Course focus adjustment : Raises and lowers stage in large increments 4 | P a g e brings image into focus Magnification : # of times image is enlarged objective X oculare=total magnification Contrast : creating the difference between similar objects measure of the difference between 2 object
