start by focusing with the lowest lens to make sure the slide is right and you can see the specimen them proceed to the next lens power and focus again just to make the view clear then proceed to the highest and focus one more time
1.Eyepiece or ocular- upper optical component that further magnifies the primary images and bring the right rays into focus.2. Draw tube- it is the cylindrical structure which is used to support the eyepiece.3. Body tube- connects the ocular to the objective lenses.4. Coarse Adjustment Knob- It moves the tube up and down to magnify thespecimen.5. Fine Adjustment Knob- It adjusts the focus slightly, to make the image clear.6. Arm- basic frame to which the base, body and stage are attached and acts as aconnector between the base and the head of the microscope.7. Stage- Table of the microscope where the glass slide is placed and helps insupporting the specimen and helps you to keep the specimen on thecorrect location.8.Stage Clip- The stage clip hold the the specimen slide firmly on the stage and isneeded if the microscope is tilted.9. Glass Slide- is the place where specimen is place to view in the microscope.10. Inclination Joint- It allows one to tilt the upper part of the microscope so thatyou can view the specimen while seated.11.Base- it helps in supporting the microscope and contains the illuminator.12.Diaphragm- it controls the amount of light that passes through the stage and,consequently, through the specimen.13.Dust Shield- It protects the objectives from dust.14.Revolving Nosepiece- This is the part that holds two or more objective lensesand can be rotated to easily change power.15.Objectives- it gathers light from the sample or object under study.16.Mirror- is used to focus light up through the hole in the microscope's stage,or slide platform. The slides will contain a thin slice of materialthrough which the light can shine, to reveal the internal structure ofthe sample.17.Mirror Rack- holds the mirror in place.
Well...... for starters.... a simple microscope has only one lens and a compound light microscope has more than one lens. They both magnify objects (or specimen) and make them seem larger than they actually are. Well that's all I got........ Buh-Bye!
You think
1) When you pick up the microscope and walk with it, hold it with two hands. Use one to hold the arm and one to hold the base. 2) Always make sure your on the lowest magnification when using it and that the stage is all the way down 3) use a chem wipe to clean everything off.. dont worry too much about the microscope slides.. if its just a plain slide they are usually not too expensive 4) Move slowly and you'll be fine.. doing everything slowly also helps the experiment run better
To make a thin and transparent specimen easier to see under a microscope, you can try using a staining technique to add color or contrast to the specimen, using a higher magnification lens, adjusting the lighting to enhance contrast, or using immersion oil to improve resolution.
A thin specimen allows light to pass through easily, resulting in clearer and sharper images under the microscope. Thicker specimens can distort the light and make it more difficult to observe the details of the sample.
Chemicals used to make specimens visible under a microscope are called stains or dyes. Stains help enhance the contrast and highlight specific structures within the specimen, making them easier to visualize and analyze under the microscope.

The diaphragm on a microscope controls the amount of light passing through the specimen. By adjusting the diaphragm, you can regulate the contrast and brightness of the image, helping to improve visibility and clarity of the specimen.
An example is methylene blue.
To focus a specimen using a low objective lens on a light microscope, start by placing the specimen on the stage and adjusting the stage height using the coarse adjustment knob until it is close to the lens. Look through the eyepiece and slowly turn the fine adjustment knob to bring the specimen into focus. Make small adjustments until the specimen appears crisp and clear.
A cover slip is a thin, flat piece of glass or plastic placed over a specimen on a microscope slide. It helps protect the specimen from dust and damage, while also flattening the specimen to make it easier to view under a microscope. Cover slips are commonly used in microscopy to provide a clear, flat surface for observing specimens.
The purpose of adding iodine solution in a fresh mount is to stain specific structures in the specimen such as the nucleus, making it easier to observe and study under the microscope. It helps to highlight the details and improve contrast.
Light microscopes can magnify objects up to 1000 times their actial size, and they are often used for dissections. Light in the light microscope allows the viewers to see the specimen that is being magnified.
