Come on! Be the first from your state to have an activity published! The EXS Stereomicroscope. Click HERE for list of all Experiments Background: You may want to look at things that can't fit on a microscope slide or that light won't pass through. To solve this problem without buying a stereo microscope, you can use your standard, light microscope with some minor adjustments: 1. First lower the stage to the bottom and lower the light condenser if your microscope has one.

Next cut a piece of cardboard to fit on your stage to protect the glass condenser lens and to keep your subject from falling through the condenser hole if any.

You will need at least one light source, but two is better. A small, flexible lamp is useful to get the best light. Flashlights can also be used, but they are difficult to keep from moving. Next find something interesting to observe that will fit under the lens. For a first try, use a penny. Place the penny on the stage and focus with the 40X.

Look at the portrait, the back, and anything else you find interesting. Next look at the bottom of Lincoln's suit in the lower left area of the penny. Here are the original artist's initials. You will need to rotate the penny upside-down however, because the microscope inverts the image. The artists' initials can also be found on the nickel and the dime in roughly the same location; I still haven't found them on the quarter.

For your next observation, remember to choose something pretty flat because you don't want to damage your scope. Also try whole insects and small rocks. But please use a piece of cardboard on your stage as recommended , and take special care when focusing that you do not ram the objective lens into your subject. Your microscope was built in such a way so as to protect you from jamming the lens onto a slide, but objects viewed in the manner described above can not be compensated for.

As a result, we recommend adult supervision when viewing larger objects such as rocks Come on!

How to Use a Microscope

NCBI Bookshelf. Molecular Biology of the Cell. New York: Garland Science;

A compound light microscope is a microscope with more than one lens and its own light source. In this type of microscope, there are ocular lenses in the binocular eyepieces and objective lenses in a rotating nosepiece closer to the specimen.

A compound microscope is often referred to as a biological microscope, but is a compound microscope always a biological microscope? You might be surprised at the answer. Read more to learn all about compound microscopes and their uses. A compound microscope is a high power high magnification microscope that uses a compound lens system.

How to observe cells under a microscope

The compound microscope is a useful tool for magnifying objects up to as much as times their normal size. Using the microscope takes lots of practice. Follow the procedures below both to get the best results and to avoid damaging the equipment. The field of view is largest on the lowest power objective. When you switch to a higher power, the field of view closes in towards the center. You will see more of an object on low power. Therefore, it is best to find an object on low power, center it, and then switch to the next higher power and repeat. The depth of focus is greatest on the lowest power objective. Each time you switch to a higher power, the depth of focus is reduced.

How to Use a Microscope Compound Microscopes Turn the revolving turret 2 so that the lowest power objective lens eg. Place the microscope slide on the stage 6 and fasten it with the stage clips. Look at the objective lens 3 and the stage from the side and turn the focus knob 4 so the stage moves upward. Move it up as far as it will go without letting the objective touch the coverslip.
