Informational resources for our visitors
Here is some information about microscopes. To find other information resources, please go to this page
With an ordinary light microscope you can magnify the view of an object from 20 - 1200 times. Usually you can choose between several degrees of magnification, by engaging different optical units on the microscope.
A microscope have a minimum of 2 optical units. The objective is near to the object to be viewed. The ocular is near to the eye of the observer. These units are typically placed at both ends of a tube in some distance from each other. Usually a microscope have two or more objectives with different magnification mounted around a rotable disk. By rotating the disk, the objective with the wanted magification can be directed over the thing to be looked at.
To focus the view clearly at the object, the microscope tube is moved up or down with a screw. Often there are two screws, one for gross focus, and another to finely adjust the focus.
Advanced microscopes can have 2 oculars so that one can use both the eyes simultanously. Advanced microscopes can also have special oculars where you can apply a camera or a camcorder. By using a camcorder connected to your PC, the image can be shown on a PC or transmitted to the internet.
It is possible to make microscopes with just one lense as objective and one as ocular. However, in order to get a picture without distortion, both units are usually made of several lenses. Different colors are refracted to somewhat different degrees. In advanced microscopes this is corrected with lenses with differnt types of glass that refract different each color differently, so that a distortion made by one lens is corrected with another lens.
Under the objective, there is a table where the object to be viewed is placed.
A microsope has also some unit that provides light, for example a lamp or a mirror, and a optical unit that concentrates the light at the object viewed - the condenser.
The light provideing units is under the table in a standard microscope, but some special microscopes is based on illumination from the side. If you want to look at a transparent object, illumination from under the table is to prefere. However, if you look at opaque objects or bulky objects, illumination from the side is to be prefered.
The object to be viewed is usually placed between two glasses, and should usually be thin. However, other types of arrangemants are possible, for example petri dishes. It is however, necessary that the part of the objects you look at do not move up or down in any degree in order to keep focus, and there should allways be some type of glass between the object and the objective of the microscope, so that the objective is not soiled or destroyed by foreign elements.
It is often possible to provide ullumination from the side at the board of a standard microscope with some kind of spotlight, but this is not feasible for all types of objects and for high magnifications.
