Types of USB Microscopes

The best USB microscopes in the market mainly belong to two broad categories -

High Power

These are the ones which offer a high magnification power which helps you observe tiny particles or organisms. Cells, bacteria, blood cells, planktons and similar specimens can be brought under such lenses. Microscopes like this are used for professional or academic purposes.

Low Power

USB microscopes with low power range are limited to showing magnified images of a bit larger things. They can be used to observe parts of an insect, minuscule imprints on a coin, weaves of fabric, sand grains on beach etc. If you have never used a microscope before, you should go for these since they are easier to use and put less strain on eyes.

Which one to buy?

Academic purpose

For studying various scientific subjects like chemistry and biology, microscopes can boost up the students’ interest exponentially. Once the students see for themselves how precise the cellular structure is on each being or how one element combines with the other in a reaction, they will start being ten times more attentive in each class. So high power microscopes are the best for them.

Healthcare 

Microscopes are absolutely necessary for the medical field to make breakthrough discoveries and continue critical researches on the delicate specimen. Here, the professionals need to use high power microscopes with interchangeable eyepieces for versatile observation. The stage or base should be large to make room for the samples.

Hobby 

For the hobbyists, they can buy whichever they prefer. But since it is just an interest, going for the ones with less price and lower power makes more sense.

Final Verdict

There are a variety of handy USB microscopes on the market right now and each of them serves a particular purpose. Find out which one of them can help you the most to reach your goal and discover exciting details of miscellaneous objects.
