The microscope is truly an indispensable tool for biologists. microscope accessories many biologists study is too small, the dwelling and performance is not seen with the human eye alone. You can get mainly two types of microscope: optical and electron microscopes. Optical microscope focused from your lens about the light, to design a magnified image, the electron beam and electron microscope focus electromagnet. Electron microscopy can resolve smaller objects, and advantages of the optical microscope.

Color and fluorescence
Electron microscope utilization of electrons and not just photons, arising under an electron microscope image is grayscale / gray scale (even so the electron microscope images are computer-enhanced contain color). On the other hand, optical microscopy, will provide color images of cells and cell structure. As one example, during the past century, scientists allow us several tips to increase the contrast of one's image from your optical microscope, student microscope they often add the dye, coupled with certain kinds of cells at the molecular (DNA, as for instance) and visualization of cell structure underneath the optical microscope. Hyperlink to their fluorescence probe labeling of antibody molecules provides another intracellular structure, when using an optical microscope to learn. Massive, scientists also have developed are readily available ., focus on "the reporter gene, as in green fluorescent protein gene interests for a particular protein for being fluorescent. Biologists can track the protein within the cell to witness it, the words does.

Specimen
The specimen is required to be carefully prepared before they could be especially observed by electron microscopy. In the act, they designed to get rid of cells, therefore cannot be used as electron microscopy study of just living cells. Conversely, many different types of optical microscope, can be used to watch the cells continues to be living and operation, which may be particularly useful an internet to recognise certain components of cell biology. And also, for your preparation on the specimens using electron microscopy techniques may make the image does not actually appear in real cells function.

Confocal microscopy
Confocal microscope, zoom stereo microscope the light beam onto a specific depth from your sample is targeted at many point. Testing equipment during a pinhole aperture in order to permit only light equipped to obtain clear images of one's specific depth inside a sample of a particular focal plane of focus reflect a biologist be included in the images, scanning the fractionated laser. Continue doing this for process to allow different deep capability to start a 3-D image of the specimen. The confocal microscope , a type of optical microscope.
