Again, why do we use compound microscope?
Typically, a compound microscope is used for viewing samples at high magnification (40 - 1000x), which is achieved by the combined effect of two sets of lenses: the ocular lens (in the eyepiece) and the objective lenses (close to the sample). ... Objective. Focus wheel to move the stage.
Somehow, what is the difference between a light microscope and a compound microscope? A magnifying instrument that uses two types of lens to magnify an object with different zoom levels of magnification is called a compound microscope....Difference Between Simple And Compound Microscope.

Anyway, where does the light come from in a compound microscope?
Illuminator is the light source for a microscope, typically located in the base of the microscope. Most light microscopes use low voltage, halogen bulbs with continuous variable lighting control located within the base. Condenser is used to collect and focus the light from the illuminator on to the specimen.
What is an example of a compound microscope?
The definition of a compound microscope is a microscope with a lens that enlarges the viewed object and an eye piece that further enlarges it. An example of compound microscope is Galileo's "little eye."

One other problem for compound microscope is that it can only magnify till certain extent. Anything smaller then that limit then we can't observe. Therefore, there are other kind of microscope suck as Electron microscopes that can observe even smaller specimens.

Bacteria are difficult to see with a bright-field compound microscope for several reasons: They are small: In order to see their shape, it is necessary to use a magnification of about 400x to 1000x. ... They are transparent: Bacteria will show their color only if they are present in a colony.

Compound microscopes are used to view small samples that can not be identified with the naked eye. These samples are typically placed on a slide under the microscope. When using a stereo microscope, there is more room under the microscope for larger samples such as rocks or flowers and slides are not required.
Solution : This is because light rays from the nearby tiny object spread over small aperture and the final image formed is very bright.
Microbes in untreated water. Using a scanning electron microscope at 2500x magnification power, bacteria, algae, sea urchin, amoeba and protozoa can be observed.
A compound microscope works on the principle that when a tiny object to be magnified is placed just beyond the focus of its objective lens, a virtual, inverted and highly magnified image of the object is formed at the least distance of distinct vision from the eye held close to the eye piece.
There are typically four objective lenses attached to the nosepiece: a 4X scanning ob- jective, a 10X low power
objective, a 40X high power (dry) objective and a 100X
oil immersion objective. The magnification of each objective is engraved on its side.
Important general rules:Always carry the microscope with 2 hands—place one hand on the microscope arm and the other hand under the microscope base.Do not touch the objective lenses (i.e. the tips of the objectives).Keep the objectives in the scan position and keep the stage low when adding or removing slides.
