What is the eyepiece?
The eyepiece is the piece you look through to see your specimen. It can be magnified to a higher power to help adjust how you see your specimen.
What is the tube?
The tube holds the eyepiece and the objective lenses at the proper working distance from each other.
What is the course-adjustment knob?
The course-adjustment knob moves the tube or stage up and down to bring your object (or specimen) into focus.
What is the fine-adjustment knob?
The fine-adjustment knob is used with medium- and high-power magnification to bring an object into sharper focus.
What is the arm?
The arm is what connects the base and the tube. You hold the arm while carrying the microscope.
What is the revolving nosepiece?
The revolving nosepiece is a rotating disk that holds 2 or more objective lenses. When the revolving nosepiece moves into place, you can hear it click.
What is the objective lenses?
The objective lenses are used to magnify an object. Each lens has a different magnification power, such as 10x, 40x, and 100x. The magnifying power is engraved on the side of each lens so identify them before use.

The stage is what holds the microscope slide. On the stage there is clips which hold the slide in its position. In the centre of the stage there is a hole which allows the light from the light source to shine through the slide.
What is the condenser lens?
The condenser lens directs the light from the light source to the object being viewed.
What is the diaphragm?
The diaphragm controls the amount of light reaching the object being viewed.
What is the light source?
