Explanation:
The Eyepiece Lens
Microscope eyepiece
The eyepiece contains the ocular lens, which the user looks through to see the magnified specimen. The ocular lens has a magnification that can range from 5x to 30x, but 10x or 15x is the most common setting.
The Eyepiece Tube
Microscope eyepiece tube
The eyepiece tube connects the eyepiece and ocular lens to the objective lenses located near the microscope stage.
The Microscope Arm

The microscope arm connects the eyepiece tube to the base. This is the part you should hold when transporting a microscope.
The Microscope Base
Laboratory microscope
The base provides stability and support for the microscope when it is upright. The base also typically holds the illuminator, or light source.
The Microscope Illuminator
Light shines through microscope
Microscopes require a light source for viewing. This can come in the form of a built-in, low-voltage illuminator light, or a mirror that reflects an external light source like sunlight.
Stage and Stage Clips
Microscope stage platform
The stage is a platform for the slides, which hold the specimen. The stage typically has a stage clip on either side to hold the slide firmly in place. Some microscopes have a mechanical stage, with adjustment knobs that allow for more precise positioning of slides.
The Microscope Nosepiece
Microscope nosepiece which holds the objective lenses
The nosepiece contains the objective lenses. Microscope users can rotate this part to switch between the objective lenses and adjust the magnification power.
The Objective Lenses

The objective lenses combine with the eyepiece lens to increase magnification levels. Microscopes generally feature three or four objective lenses, with magnification levels ranging 4x to 100x.
The Rack Stop
Rack stop
The rack stop prevents users from moving the objective lenses too close to the slide, which could damage or destroy the slide and specimen.
Condenser Lens and Diaphragm

The condenser lens works with the diaphragm to focus the intensity of the light source onto the slide containing the specimen. These parts are located under the microscope stage.

How to Handle a Microscope

Microscopes are devices used to magnify small objects, allowing them to be seen by the naked eye. Most microscopes have several different powerful lenses attached to them, allowing the viewer to inspect the content at more than 100 times its actual size. However, microscopes are extremely expensive, so you want to make sure you handle the device properly.
Hold the microscope with one hand around the arm of the device, and the other hand under the base. This is the most secure way to hold and walk with the microscope.
Avoid touching the lenses of the microscope. The oil and dirt on your fingers can scratch the glass.
Clean smudges on the microscope glass with a piece of lens paper. Any other material, such as tissues or even cotton, can scratch the glass of the microscope.
Rotate the nosepiece of the microscope all the way down to its lowest level when you have finished using the microscope. If you leave the nosepiece up while storing it, the gears on the device can wear out. If this happens, the nosepiece may not be able to lift and hold its position.
Cover the microscope with the dust cover to protect it from dirt and other debris.
