Pick your next microscope

A microscope is one of the most basic yet exciting tools to use This instrument enables a doctor or a scientist to magnify an object and study it in detail. Different types of microscopes allow for different levels of resolution and generate different types of images. Some of the really advanced microscopes can even visualize atoms.

Compound Microscope

A compound microscope is the most well known type of optical microscopes. It makes use of multiple lenses to give a magnified image. A normal compound microscope comprises of a viewing lens that serves to magnify an object up to 10  times. In addition to this, there four other secondary lenses that can magnify an object up to 15, 40, or 100 times. Light is positioned below the sample. It then moves through one of the secondary lenses and then the viewing lens, and is thus twice magnified. For example, if you use the 40x lens along with the 10x viewing lens, the sample you are viewing will be magnified 10 into 40, i.e. 400 times.

Dissection Microscope

Another type of optical microscope is the stereo or dissection microscope. This microscope makes use of two distinct viewing lenses and generates three dimensional images of the object under examination. However it has a notably smaller m magnification power as compared to a compound microscope, and typically cannot magnify greater than 100 times.

Imaging Microscope

These microscopes have a comparatively higher magnification and resolution than the optical microscopes, however they are much more costly. Various types of imaging microscopes make use of a variety of particle or radiation beams in order to generate an image of the sample. Confocal microscopes utilise laser light, scanning acoustic microscopes utilise sound waves, and X-ray microscopes, as the name indicates, use X-rays. Electron microscopes utilise electrons and can magnify an object up to an astonishing 2 million times. The transmission electron microscope generates a two dimensional image, whereas the scanning electron microscope gives us a three-dimensional one.

What to consider when buying a hobbyist microscope?

Obviously you need to pick a compound or a dissection microscope. Look at:

  • Price
  • Materials
  • Illumination
  • Magnification

Start your search by looking at microscopes which have a well-built frame. The best of them are made of metallic alloys that keep vibration to a minimum and prevent fluctuations which occur due to temperature variations. If you are considering to buy a microscope made up of plastic, then simply don’t. The reason being that it will not provide you with the optimal performance of your expectations, let alone hold up over time.

The build of a microscope has a drastic impact on its longevity. A microscope with a finer basic build will obviously last longer, thus saving you money in the long term. Try finding a frame made up of metallic alloys, since they minimize vibrations, along with limiting the effects that fluctuating weather can have on a microscope.

You should consider buying microscopes that have metal focus gears, metal screws, optical glass lenses, reagent resistant finish, and ball bearings in their revolving components. Beware! A number of toy microscopes in the market are painted or chromed in such a manner that they look exactly like metal. Thus one needs to be careful.

Illumination and magnification are of course your key parameters to consider.
