Ocular

Magnifies the image. Typically magnification of 10x.

Pointer

Located in one of the oculars and is used to point to structures and features found in the image. Typically found on the right ocular.

Base

Support and stabilize the microscope.

Arm

Connects the base to the head/body.

Head/Body

Holds the ocular lenses and rotating nosepiece.

Rotating Nosepiece

Holds the objective lenses.

Objective Lens

Magnify the image. Only one can be used at a time.

Scanning Lens

4x Magnification

Low Power Lens

10x Magnification

High Power Lens

40x Magnification

Stage

Holds the slide and has a hole to allow light to pass through the slide.

Stage Clip

Secures the slide to the mechanical stage.

Mechanical Stage

Safely moves the slide around the stage.

Mechanical Stage Knobs

Moves the mechanical stage.

Fine Adjustment Knob

Focuses the image by changing the distance between the slide and the objective. You may use this with all lenses.

Coarse Adjustment Knob

Focuses the image by changing the distance between the slide and the objective. You may only use this with the scanning lens.

Iris Diaphragm

You can regulate the contrast and resolution of the image by opening or closing this.

Condenser

Concentrates the light that comes from the light source.

Light Source

Provides light.

Rheostat

Regulates the light intensity of the light source.

Power Switch

Turns the microscope off and on.

Power Cord

Provides electrical power to the microscope.
