A compound microscope is a microscope fitted with two or more convex lenses. The high magnification produced by these lenses together enables a detailed study of micro-organisms, cells and tissues. These types of microscopes are therefore widely used in scientific and medical research. The basic design of a compound light microscope consists of convex lenses fitted at either end of a hollow.

The first one Is the electron microscope while the other is the light microscope. The first type of microscope is the light microscope. This type of instrument utilizes natural or artificial sources of light to illuminate an object and then magnify it through the use of lenses properly and precisely placed together.

Light Microscope Essay

Light microscopes employ optical lenses to sequentially focus the image of objects, whereas electron microscope uses electromagnetic lenses. Light and electron microscopes work either in transmission or scanning mode depending on whether the light or electron beam either passes through the specimen and is diffracted or deflected by specimen surface.

Light Microscope Essay

This microscope contains one or more lenses to produce an enlarged image of a sample placed in the focal plane. This microscope has refractive glass and occasionally of plastic or quartz, to focus light into the eye or another light detector. This microscope is mainly used in the more professional field of science. No matter what microscope it.

Compound microscopes provide several objective lenses with different levels of magnification and a light source for illuminating specimens. Compound microscopes are limited to a maximum magnification of about 2,000x the specimen's size; theoretically, they can go higher, but the human eye and brain cannot process the information.

Light Microscope Essay

Visible light restricts the amount of resolution achieved with a light microscope. Magnification may range from 500x to 1500x, which is much smaller in comparison to electron microscopes; these give magnifications of 160,000x or more. In general, light microscopes require specimens to be thin, small and transparent for optimum viewing. The.
