Microscope

Front 1

Ocular (eyepiece)

Back 1

Uppermost lens; magnifies objects 10 times their size (10x(

Front 2

Head

Back 2

Holds the oculars

Front 3

Prism slider bar

Back 3

Directs the beam of light by moving the prism inside the head; it has three positions:
1: all the way in - light 100% to oculars
2) midpoint - 100% of light to computer
3) all the way out - splits the light beam 50/50 between scope & computer

Front 4

Nosepiece

Back 4

Revolving part to which the objectives are attached

Front 5

Objectives

Back 5

Set of four lenses attached to the revolving nosepiece. Objective lenses are always used in order: scanning, low, high-dry, oil immersion. The magnification of the ocular objective is labeled on its side. Total Magnification is equal to the magnification of the ocular lens time the magnification of the objective lens.

Front 6

Stage

Back 6

Supports the slide over a hole that admits light from the light source. The stage clip holds the slide firmly in the desired position.

Front 7

Mechanical Stage Knobs

Back 7

Two knobs located below the stage; one controls forward/backward movement of the slide, and the other control right/left movement.

Front 8

Rheostat

Back 8

Knob located on the right side of the base that regulates voltage and light intensity. Use a medium rheostat setting.

Front 9

Condenser

Back 9

Lens system located beneath the stage, it focused light onto the specimen; the condenser should always be in its highest position.

Front 10

Condenser Adjustment Knob

Back 10

Located below the stage, the condenser should always be in its highest position.

Front 11

Iris Diaphragm

Back 11

Regulates the amount of light passing through the specimen; located beneath the condenser, controlled by a lever.

Front 12

Coarse Adjustment Knob

Back 12

Used for preliminary focusing by lowering the stage; used only with the 4x scanning and 10x lowe power objectives.

Front 13

Fine Adjustment Knob

Back 13

Used for final or fine focusing by raining or lowering the stage.
