It’s understandable for someone who is looking to buy a microscope to become quite overwhelmed by the choices and we know this can be quite off-putting.
There are so many factors to take into consideration which may depend on what you are planning to use the microscope for as well as your age and profession or study.
That’s why we have put together this guide so that you can get an overview on what’s available in the market and a look into the type of microscope which fits your needs before you make a purchase.
You don’t have to worry about having any particular background knowledge or have to work in a professional capacity to buy a microscope as they’re so often used by people at home and professionals alike and it’s certainly a great way to encourage and maintain a kid’s interest in the sciences; which is so important in today’s STEM-focused job market.
If you already have your microscope, whether you are a beginner hobbyist or parent of a child and you are not sure exactly what you are doing, head on over to our guides on how to use a microscope and the parts of a microscope to really get acquainted with your new bit of kit.
For the uninitiated, there are two types of microscope: the low power and high power.
Although both are useful for the applications they were designed for, high power microscopes are more popular not only to professionals, but to hobbyists and children as well. This can be attributed to the fact that “invisible” things can be observed, thus presenting a more exciting experience for the user.
High power microscopes on the other hand are used to look at things that are way too small for the naked eye to see.
Examples include blood cells, bacteria and tissue. Also called compound microscopes, high power microscopes are able to magnify objects up to 1000x.
Low power microscopes are essentially used to look at larger objects such as rocks, coins, insects, stamps, rocks, soil, fabric weaves, and the like.
They are also called “Dissecting” or “Stereo” microscopes. Stereo microscopes have dual eye-pieces and have the capability of magnifying specimen 10x to 50x. In effect, the user can view the object in three-dimensions.
The Importance Of The Light Source
What most beginners forget is the source of light in every microscope. A good light source means that one is able to view specimens in a very detailed manner, with clearer and better image quality.
Microscopes available in the market today typically have a built-in light source, although a common entry level microscope might use a mirror in order to outsource light from the environment.
Those with illumination fresh out of the box may have halogen bulbs, fluorescent, tungsten, or LED. Tungsten systems are more affordable than the fluorescent bulb, but the latter heats up less and is significantly brighter.
The majority of modern light microscopes contain halogen lighting, since it produces a strong, white light and usually comes with a rheostat to allow the light levels to be altered with ease.
Fluorescent microscopes are typically found in highly specialised scopes that are used for molecular and biological research. Thee help the researchers observe fluorsecent tags such as fluorophores commonly used in research.
Light Emitting Diode systems on the other hand provide multiple advantages and are by far the latest technology in microscope illumination. While, LED microscopes eat less power and heat up less. A LED microscope can also be cordless, since these microscopes can be powered with batteries.
Digital microscopes can be either be stereo or compound. What puts the digital variety up on the pedestal is their ability to capture both still and video images.
The captured images can be displayed in an external monitor after observation. In some schools, digital microscopes with built-in LCD screens are becoming a favorite among students and teachers.
The reason for which lies in the fact that images are automatically seen onscreen, which makes sharing information easier and faster, providing an interactive, learning experience.

Which Microscope Should You Choose?
Given the numerous options one could go for, your decision depends on where and how you intend to use it, essentially.
However, although a low power microscope serves its purpose, what would be a more enjoyable experience is for a first-time buyer to purchase a high power microscope. This would also ensure you could enjoy your microscope far into the future as you continue your learning journey.
Having established the fact that the resolution and magnification power is much better in compound microscopes, this is a good enough reason to opt for one over a stereo-microscope.
Even children can benefit greatly from such endeavor, since it provides them with a learning experience on a whole new level, which is bound to leave them with a lasting mark and passion for science. More to the point, compound microscopes are usually the instrument preferred by most schools.
The above-mentioned models are recommendations for first-time buyers. It should be noted that there are still a hundred or more models of stereo and compound microscopes that one can choose from. The real choice is all yours to make.
