Types of Microscopes

Microscope is one important tool that is functional to see objects or organisms that are so small. Along with the progress of science and technology, types of microscopes and zoom capabilities experience the advance.

There are two types of microscopes; light microscope and electron microscope. Light microscope include bright field microscope, dark field one, phase contrast one and florescent one. Microscope that is often used in secondary schools for the practicum is bright field microscope.

Bright field microscope is a microscope with a field (field of view) that surrounds the specimen appears bright, while the specimen looks darker. This is because light from the source (mirror or lamp) passes through a lens system to the top without experiencing a change, thus it forms the bright field.

Microscopes in common use today use two or more lenses (lens system) such as ocular and objective lenses to enlarge the object. The types of this computer range widely, from a simple one for the purposes of secondary school up to a fairly sophisticated one for research purposes.

The main characteristic of the microscope today among others is monocular with the upright and tilted tube, binocular, trinocular, the power of the lens that is used, the light source (using a lamp that is attached), and even the camera that can be mounted (video camera) on trinocular microscope and can be connected to your TV.

Meanwhile, electron microscope has the highest magnification. It can amplify a tiny thing up to 500.000 times. It uses electron in the place of light in light microscope.

There is also microscope for kids. Now, once you have this set up, you and your kids can spend all kinds of time looking at random stuff under the microscope. You can also make sure that your kids have a chance to really experience science. Find for complete information about it on microscope for sale.

Why an image appears inverted and reversed through a light microscope?

I've been looking at dozens of pages and have yet to find a detailed answer. I need something beyond because 'light rays form a cross as they pass through the lens, projecting an inverted and reversed image'. This really doesn't explain much. Help x-x Even a decent reference would help.

A single lens will create either a virtual image that's right side up (like holding a magnifying glass close to something) or a "real" image that's upside down but can be projected onto a surface (like using that magnifying glass to make a tiny image of an overhead lamp on the table).

What telescopes do is create a real and upside down image with the first lens, and then flip it again with the second lens, so everything's right-side up. But this only gets you 10-40 times the magnification with commonly available lenses.

If you arrange the lenses differently, though, you can get a much larger magnification but only one of the lenses creates a real image, the other makes a right-side-up virtual image. So the image is flipped once, and ends up upside-down, rather than being flipped twice as in a telescope.

Trichodesmium : The world's most famous nitrogen fixer
Editor's Note: Journalist and crew member Kathryn Eident and scientist Jeremy Jacquot are traveling on board the RV Atlantis on a monthlong voyage to sample and study nitrogen fixation in the eastern tropical Pacific Ocean, among other research projects. This is the sixth blog post detailing this ongoing voyage of discovery for ScientificAmerican.com . Imagine you’re in space, floating high ...
