The microscope is a particular optical device that allows you to explore the world on smaller scales, providing a decidedly powerful magnification. It is a product that many associates only with scientific use, but, over time, many people (even non-scientists) have started to buy it out of a pure hobby or out of curiosity. Biological microscopes are the best known and most used model, and we will refer to this typology, whether it is a device for beginners or experts.
But choosing a microscope, especially if you are just a beginner, can be very difficult, because there are many features to consider, and the types of microscope are just as numerous, each of which is suitable for a certain type of person.
In the market, there are many microscopes for sale, of the best brands or cheap, and making the most prudent choice before clicking the “buy” button could be a more complex thing than it seems.

Buying Guide to Select the Best Microscope
Before diving into the illustration of the main factor to evaluate in choosing a microscope, or its magnifications, we must make an important clarification: we will deal here only with biological microscopes, also called scientific microscopes. This is the type of microscope dedicated to observation at the cellular level; therefore, they are instruments with a high number of magnifications and backlit.
First, we need to consider the total magnifications of a microscope, which are obviously very important to allow us to observe exactly what we want to observe. If we want to go down to the cellular level, we need at least 400 magnifications, but if what we need is a microscope for microbiological studies (at university level), we will have to go down to 1000 magnifications.
There are not many models that enlarge more than a thousand times, but among the high-end ones for private use, you can find someone who reaches up to 2000 enlargements.
Among the technical specifications of a microscope, you will always find the minimum and maximum magnifications of which it is capable: it can go from 20 minimum to 2000 maximum, but most of the models on the market have a range from 40 to 1000 magnifications.
Eyepieces and Objectives
The total magnifications of a microscope are given by the magnifications of the eyepiece and those of the objective. The eyepiece is the tubular part of the microscope on which the eye rests to observe the slide and can be single, double, or triple. The objective is instead, the lens that is pointed towards the sample to be observed. The vast majority of eyepieces have ten magnifications, but a second 15 or 20 magnification eyepiece can also be found in some high-end microscopes. The goals, however, are usually more than one. Single-lens microscopes are very rare and very “basic.” The most common combination is that of 10, 40, and 100 magnification objectives, but in the models with four objectives, the one with four enlargements is added.
As with all optical instruments, the quality of the lenses and optical units of a microscope is of fundamental importance in determining their performance. There are many elements that come into play, and we will try to mention only the main aspects that those who want to make “serious” use of the microscope should take into account.
The materials in which the microscope lenses are made are the most important thing to evaluate. In fact, there are many very low cost microscopes on the market, which we can consider toys or little more, equipped with plastic lenses: these not only allow a smaller number of magnifications, but they greatly compromise the sharpness and quality of what you can to observe. Anyone who needs a microscope for study or to cultivate their scientific interest will necessarily have to choose a model with glass optics.
Correction of Aberrations
However, it is not enough to have glass lenses to have a high-quality microscope: it is also important that the glass and the lens construction, in particular, are such as to correct the optical aberrations that inevitably form when light passes through different lenses and different chambers air. The two main aberrations to be corrected are:
Chromatic aberration: colored halos form at the edges of the image
Spherical aberration: the edges or center of the image are blurred
Chromatic aberration microscope
For the correction of the chromatic aberration, low refraction and low dispersion glass lenses are needed, which better convey the light beam without disuniting it in the different frequencies, thus generating colored halos.
There are three types of optics designed for color correction: achromatic objectives, fluorite objectives (also called semi-apochromatic), and apochromatic objectives. Among these, achromatic lenses are those that correct less distortions and have an affordable cost, while apochromatic lenses correct all distortions and have a very high price. Fluorite lenses represent a good compromise between correction and cost.
For the correction of the spherical aberration, which is particularly accentuated with apochromatic lenses and is particularly annoying for cellular photography, a so-called planar lens is necessary, which “flattens” the focus of the image and therefore allows a homogeneous focus.
Of course, there are objectives that correct both distortions: they are called plan achromatic if the achromatic lenses are combined with the planar objective and plan apochromatic if the lenses combined with the planar objective are apochromatic.
Secondly, it is clear that today a microscope can integrate information technologies that were once unthinkable so that the possibilities of observation are now expanded. Buying a microscope today means having more options than ever before; let’s see what these are.
Some models replace the classic eyepiece with an LCD display: this, therefore, allows you to observe the samples without having to stoop over the microscope and to capture photos and videos of the observed sample. Microscope LCD Images can be saved to a local memory or downloaded via USB connection. On the other hand, electronic image processing can introduce a level of uncertainty in the observation of details. The LCD microscope allows the observation of more than one person at the same time; for this, it can be an excellent educational choice: a parent who wants to follow their children in their first microscopic observations can do it very easily with a microscope of this type.
Several modern models can be connected directly to the computer and thus become accessible as a system peripheral. The connection is normally made via USB cable, and there is a built-in microscope camera that allows the transmission of the image directly on the computer screen (and from here, if desired, to a projector or TV). “Classic” observation is always possible since the optical eyepiece is always present.
A PCA cheaper variant is the inclusion in the microscope equipment of a special eyepiece for computers: in these cases, these are “normal” microscopes on which, however, an eyepiece with a camera can be connected to the computer. If the microscope is trinocular, that is, it has three eyepieces, it is possible to attach the camera to the eyepiece on the top and continue the first-person observation through the binocular.
Microscopes of this type are particularly convenient for teaching since they allow sharing the observed sample with a very large number of people.
The possibility of choosing a “pure” microscope is of course always open: those who have home study needs that do not require the “sharing” of what they are observing nor the shooting of videos and photos will be very well with an “old-fashioned” microscope, “without PC eyepieces and without LCD display.
For the observation of biological or microbiological samples, it is necessary that these are prepared so as to be transparent or translucent, and above all, they must be backlit: it is not possible to observe an opaque body, such as a coin or a pebble with a biological microscope. The illumination of the sample is, therefore, of fundamental importance for the functioning of the microscope.
The Type of Lamp
“Mirror” microscopes are no longer available on the market, that is, those that use the refraction of an external light beam to backlight the samples. With what we are about to explain, it will also be clear why: it is much easier to finely control the light beam if it comes from an integrated and controlled source. Modern microscopes, therefore, use an integrated lamp and a light beam control system.
There are basically two types of lamps that can be found on a microscope: halogen lamps or LED lamps. The first type of lamps have a higher electrical consumption and generate more heat, while the second type lamps have a much lower energy consumption and heatless. In both cases, the generated light must be white, and any change in color, which can be used in some cases to improve the photographic quality of the observation or to better distinguish some samples, occurs through the use of special colored and treated filters.
A good microscope should offer the possibility to adjust the intensity of the light beam, regardless of the type of lamp mounted. In fact, depending on the sample we want to observe, we may need less or greater brightness, depending on the density and opacity of the sample itself or even just to better observe some details by changing the light intensity during the observation.
The condenser is a system of lenses whose task is to convey the light in a light beam that hits the sample at the right angle and then reaches the target to reach the eye. The condenser must also be adjustable; that is, it must be possible to modify the incidence of the light beam in order to hit and perfectly illuminate any sample. Since the condenser is an optical system, it is also subject to the same aberrations that can be generated in a lens; for this reason, also the lenses of a condenser can be corrected. There are basically three types of capacitor that can be found:
Chromatic capacitors: the cheapest and simplest, most of them are of the Abbe type, with only two lenses. These capacitors do not provide for any aberration correction
Planar capacitors: these capacitors correct spherical aberration
Achromatic condensers: these condensers correct chromatic aberration and usually also spherical aberration
The lamp can be powered in three ways: by the battery, from the network or via USB cable. It clearly depends on what type of microscope it is: “pure” microscopes are in many cases battery-powered, those with LCD power supply and those from PC through the USB cable connected to the computer.
To complete the overview of the fundamental parts of a microscope, we must necessarily also talk about the translating table. This is the support on which the slide with the preparation to be observed rests and is fixed, and this can also have a greater or lesser level of sophistication.
In the case of cheaper microscopes, the table is equipped with two simple clips that hold the slide in place, and any movement of the sample, to observe another portion, must take place by hand in a very imprecise and often too abrupt manner.
Translating Table Microscope
A good microscope, on the other hand, has a mechanical table, also called a cross table, with a translator to attach the slide to two mechanical screws for moving the slide in the four directions and a reference graduated scale.
The table has an opening through which the light beam generated by the lamp, and the condenser below passes. This opening in the less sophisticated microscope models is a simple hole, but in more complex models, it can be equipped with a diaphragm: this comes into play when it is necessary to reduce or widen the light beam coming from the condenser. It must be said, however, that the simpler condensers, the Abbe or the chromatic ones, often have an integrated diaphragm.
Finally, a microscope can have a more or less rich accessory kit, depending on whether it is an instrument intended for people who are already experts in microscopy, who will therefore not need a package full of preparations and instruments to start, or a product intended to beginners, especially children, who therefore provides everything needed to learn how to use the microscope.
Here are the most common accessories that you can find supplied with a microscope:
Getting started: not to be confused with the instruction booklet, the guide is intended for beginners and/or children who are about to learn to use the microscope.
Ready-to-use preparations: beginner microscopes are always accompanied by some slides already prepared and ready to be observed.
Empty slides: they are supplied to many microscopes, both for beginners and experts.
Preparation tools: a kit of tweezers, pipettes, scalpels, vials, Petri dishes, etc. it is found in almost all beginner microscopes.
Samples to prepare: microscopes for beginners and children are always accompanied by microorganisms to prepare and observe.
Interchangeable eyepieces: in the medium-high range microscopes, you can find two or three eyepieces with different magnifications.
Lens covers: the good models have covers to protect the eyepieces from dust.
Filters: microscopes for experts also have a series of colored and treated filters, in some cases integrated into the microscope itself, which modify the light spectrum emitted by the lamp. They are useful for particular types of observation and for photography.
