1. Turn on the illuminator. When using the dimmer, it is best slowly increase the light intensity as the lamp heats up quite quickly.
2.Place a slide or specimen on the stage with the sample directly above the aperture and, if possible, fasten it to the stage with the stage clips. Reminder: A cover slip is always needed to allow for the best quality image.
3.Ensure the iris diaphragm is completely open, allowing the maximum amount of light to reach the slide and the lenses. Caution: Do not use the iris diaphragm to control the light, it is to control resolution and contrast - use the dimmer instead.
4.Rotate the nosepiece so that theobjective lens with the lowest level of magnification is directly above the sample. Reminder: Using lower magnifications first helps to select the part of the specimen of interest and then adjust further.
5.Look through the binocular eyepieces and adjust the iris diaphragm until the amount of light is satisfactory. More light is better than less light, but the comfort of the viewer's eyes should also be taken into account.
6.Turn the coarse adjustment knobuntil the specimen comes into broad focus. Caution: you should not use the coarse focus with a high magnification objective for fear of the objective making contact with the slide.
7.Turn the fine adjustment knob until the specimen comes into sharp focus. Caution: should not take a long time to find focus, otherwise the high magnification objective could also hit the slide. If you are having a difficult time to find focus then restart with the lower magnification objective.
8.The viewer should then be able rotate the nosepiece to higher settings and bring the sample into more and more detail with a minimal amount of refocusing.

Can a water molecule be seen through a compound light microscope?
No
How do you clean a compound light microscope?
use alcohol to clean the lens
What major advantage does a transmission electron microscope have over a compound light microscope?
The Compund light microscope allows people to view living cells. With the electron light microscope peole can only view dead cells but with very high detail. The electron microscope is also much more expensive than a compound ligh microscope. The compound light microscope is also much easier to transport from place to place, as the electron microscope is not.
How does a compound microscope use lenses to magnify an object?
the optical microscope is a type of microscope that uses visibal light and a system of lenses to magnify images of small samples
What is the difference between a compound microscope and an electron microscope?
Compound microscopes (also called compound light microscopes) employ light and an array of glass lenses to magnify an object. (This is distinguished from a simple microscope of one lens.) An electron microscope uses a beam of electrons to magnify an object. The lensing system employs electric and magnetic fields and is specialized for applications requiring much higher magnification. See related links.
What is a light microscope that has two more lenses?
A compound microscope
When using a compound light microscope and focusing should the lowest power lens should be used?
yes it should.
What type of microscope aside from the compound light microscope might you use to observe the organisms found in pond water?
compound light microscope
An instrument that produces images by focusing light rays is called a?
a magnifying glass, a telescope or microscope all do this.
What came first electron microscope or light microscope?
compound light microscope - cell theory - electron microscope
Why light microscope also called compound microscope?
Light microscopes are called compound because a light microscope has more than one lense.
What is the BEST procedure for focusing a compound light microscope?
