Find basic definitions for common microscopy terms, information to help you understand differences between magnification and resolution, and how fluorescence can be used to improve contrast and increase resolution. Topics in this section ...
What is a Light Microscope? In this lesson, find the light microscope definition and function. Read about what a light microscope is used for in application. Related to this Question How do you calculate the total magnification of a microscope?
As a student of science, you may find yourself in the position of having to count cells under a microscope for one reason or another. These might be red blood cells, or bacterial cells, or some other kind of cell or (commonly) a mixture of cell types. Can you think of any reasons t...
The lenses are replaced by a series of coil-shaped electromagnets through which the electron beam travels. In an ordinary microscope, the glass lenses bend (or refract) the light beams passing through them to produce magnification. In an electron microscope, the coils bend the electron beams the...
'How To' Guides By Type By BrandHow Does a Microscope Work ?A great deal of optical science is involved in answering the question "how does a microscope work?" A simple microscope has one lens and is essentially a loupe or magnifying glass with a relatively high magnification. ...
How to find the mass number of an isotope?What are Isotopes?Isotopes are different 'versions' of an element differing in the number of neutrons found in the nucleus. The atomic weight for an element is usually not an integer as it is the weighted averages of all the isotopes of that ...
When you begin using thebiological compound microscope, always begin with the 4x objective lens (the lowest magnification). This will allow you to focus on your sample and help prevent you from smashing your objective lens into the stage. Move up one objective at a time, refocusing each time...
Of course, that's not to say that watch aficionados will tolerate lesser accuracy for the sake of a pretty piece of wrist jewelry. A watch is a tool first and foremost, and its ability to display reasonably accurate time is the key feature that differentiates it from a mere bangle. Some...
3x3 grid of major squares. Each major square is 1 mm x 1 mm, and the height of the chamber is 0.1 mm, so the fluid volume above each square is 0.1 μL. A low-magnification microscope (usually 10x) objective lens will allow one of the squares to be positioned in the field of view...
a dark center, or nucleus. To see more of the cheek cells in detail, you'll need to increase your microscope's magnification. Try changing the light microscope's magnification to X-100, then turn the focusing dial to refocus the lens for image clarity if necessary. Now that you've ...
