Want to Get a Used Microscope?

Remember back to your school days when you first saw amoeba swimming around pond water?  You were likely  thrilled to see microscopic organisms moving, colliding. Now you want to share memory with your children or grandchildren as they grow. But you do not want to spend their college money on a new microscope with a high price, so what can you do? No problem – you can now find many microscopes that are used or demo models to a much more reasonable price. But first you must determine what type of microscope that you want used: compound or stereo / dissection. 

The most common microscope is the compound microscope. That’s what most people visualize when they think of microscopes. It comes with an eyepiece called monocular, binoculars or eyepieces called may have another tube with a camera and is called trinocular. Has a number of objectives (the lens closest to the object being viewed) of different magnification mounted in a swivel spout. It uses a light source below the stage to illuminate the slides. These microscopes are typically used to view very small objects such as bacteria or cells mounted on slides. Enlarging these areas range from 40X to 1000X. effective magnification can be calculated by multiplying the power of the eyepiece by the power of the objective lens. 
The other type of microscope is called stereo or dissecting microscope. It uses two eyepieces and two objectives associated. There are models that have the ability to zoom and full models that have only just two magnification settings. It is surely very useful for performing dissections biologists, construction or repair of electronic boards, paleontologists cleaning and examining fossils or one who needs to work with the hands of small objects such as rocks and bugs. You can use a built in light source from above, below, or none at all. Magnification is usually from 10X to 40X. 

By researching and buying used microscopes opens a much greater range of tools at your disposal. You can now buy an instrument with many other accessories for much less money. Just make sure you do your homework ahead of time so you know what to expect for the money to pay.
