For a biologist, who plans to find solutions for diseases, four main types of microscopes are used for research.
They are the dissection, the compound, the scanning electron, and the transmission electron microscope. The transmission and scanning electron microscopes both used electrons and their excitability so as to view objects.
The scanning Nikon Instruments microscope sees pictures in 3D and the transmission one sees them in 2D. A dissection one helps one to see larger images so they can be dissected. The compound is most popular and allows one to see the image in the cell level, unlike the dissection scope.
They are extremely large and both focus on a vacuum in order to see items. Another type of research microscope is the confocal microscope. Browse http://www.technospex.com/calculator/ to get more additional details on Spectroscopy calculation.
It is a step down from the SEM and the TEM, but is still too expensive and complicated to be found in most universities.
A confocal microscope uses a laser beam to enhance an item, which can be seen on a computer screen. What makes them like the high school microscopes is that items are placed on microscope slides and at a solution, so as to be viewed.
Researchers use a microscope for various reasons. Sometimes it would be to unravel mysteries that have confounded scholars for millions of years. Other times, it may be to help solve a disease puzzle that's plaguing the world.
The world today has become so high tech that many have yet to understand exactly what it is that researchers do behind the scenes until their final product is seen.
