Construction, care, and maintenance  of compound microscope

Construction:

• A compound microscope consists of two convex lenses. The lens towards an object is called the objective lens and the lens near the eye is called the eyepiece. The focal length of the objective lens is less than the focal length of the eyepiece. This combination forms the magnified image of the object.

• A compound microscope is defined as a microscope with a high resolution and uses two sets of lenses to provide a 2-dimensional image of the sample.
• The term compound refers to the usage of more than one lens in the microscope. Also, the compound microscope is one of the types of an optical microscopes. The other type of optical microscope is a simple microscope. The difference between a simple and compound microscope is that a simple microscope uses only one lens while a compound microscope uses more than one lens.
• The compound microscope is mainly used for studying the structural details of cells, tissue, or sections of organs. The parts of a compound microscope can be classified into two:

Non-optical parts

Optical parts

Non-optical parts

Base

• The base is also known as the foot which is either U or horseshoe-shaped. It is a metallic structure that supports the entire microscope.

Care and maintenance:

• Handle with care

If the microscope must be moved, carry it from the base and support arm, if picked up by stage or eyepiece holder it can become misaligned.

• Keep covered

Every time you use or clean the microscope be sure to cover the kit to prevent dust and other contaminants from reaching the apparatus. If you cannot find your cover, order a new one from the manufacturer or find a suitable substitute, such as a large plastic bag.

• Store safely

Keep the microscope in a draft-free, dry place, where it won’t get bumped, pushed, wet, and where things will not fall on it. Make sure the microscope is level with the table/bench.

Keep area clean

Keep the area clean, organized, and ready to use for the next person, even if that’s you: throw away used lens paper/wipes, cover any bottles, wipe the counter clean and place essential items within easy reach for the user.

Keep the stage clean with lens paper to remove dust and particles, you can use a little alcohol to remove oil and other dirt if needed.

A small soft brush or canned air can be used to dust off the microscope – use carefully.

Do not prepare or stain samples next to the microscope.

• Keep the lenses clean

Clean off the oil immersion lenses with lens paper after each use. This should be done routinely after every use with no exception because the oil gets sticky and attracts dust and dirt. Some labs may use a solvent to remove oil, others use a bit of alcohol, but always use manufacturers' recommendations.

Only use lens wipes/lens paper. Do not use a tissue, paper towel, or any other types of wipes – they will scratch the lens.

Don’t forget to clean the ocular lens in the eyepiece, it can become dirty from eyelashes, makeup, and fingers. The objective lenses will also need to be cleaned periodically, again follow the microscope manual or have it done by a professional.

• Take care of bulbs.

Turn the microscope off after use. Do not keep the light on all day as this will shorten the bulb’s life.

Always have extra bulbs handy, not just one but at least two. You don’t want to turn on the microscope to look at your oh-so-important cells only to find a blown bulb, you then try the new bulb and it’s bad, ugh. Believe me, it can happen.
