There are two main categories of microscopes – biological and stereo microscopes. They are often simply called high-magnification and low-magnification devices respectively.
Biological microscope

If you are planning to observe “smaller” samples, such as blood samples, bacteria, microbes from the pond, aquatic organism and similar organisms you should select a biological microscope. High magnification properties are required to see the essential details of these small samples. This is why such microscope is called a biological microscope. A biological microscope usually has 3 to 5 lens heads with magnification properties that ranger between 4x and 100x.

If you choose to acquire such a microscope, you will have to decide whether you need a monocular, binocular, or trinocular device. We offer Delta Optical Biolight 300 (click on the figure on the left side to find a link to this microscope) or Delta Optical BioStage II (a link to the description of the microscope is at the bottom of the page) to be acquired for affordable price.

Stereo microscopes

Choose a stereo microscope if you are planning to observe large specimens, such as insects, leaves, stones, precious stones, tiny electronics, amber, etc. Such specimens usually do not require high magnification. Therefore, magnification up to 60 through 80 times is fully sufficient. Stereomicroscopes often have at least two eyepieces (binocular) and provide a 3D image. Like biological microscopes, stereo microscopes may have a third optical pipe (trinocular) that is designed for camera mounting – for making photos or video material. Delta Optical StereoLight is a device that meets such a type of microscope for affordable price. If you require a slightly higher magnification, we offer Delta Optical Discovery 30. And if you work with bigger items, Delta Optical Discovery L can be the right choice for you. These microscopes can be acquired by clicking on the appropriate links at the bottom of the page.


Microscopes cover a very wide price range – from toy microscopes that cost just a few tens of euros to professional models of German and Japanese manufacturers which can cost as much as a new car. Toy microscopes are of course not suitable for serious use, and you may not afford spending thousands of euros on the top class devices. Fortunately, you may choose from a happy medium – inexpensive top class microscopes that fall within the price range from 100 to 1000 euros. We will focus on this category.
Microscopes of high magnification functionality are the most popular among children, microscopy enthusiasts and are perfects for general use. They are perfect choice if you want to see a really “invisible” world, for example, blood cells, amoebas or bacteria.

We do not recommend cheap plastic microscopes if you plan to buy a microscope for a child. Such devices can exasperate your child and discourage your son or daughter from a new hobby. More serious microscopes have a metal construction and glass lenses.


If you have decided what type of microscope you need, there are several variables that you should consider. Quality is the most important of them. The quality usually defines durability of the construction, lenses and lighting.

Quality of assembly. It is generally believed that a more expensive apparatus will have a higher quality of assembly. This is partly true. But such a characterization is too poor. Even though the apparatuses that cost a four-digit amount ensure simply flawless accuracy, there also exist microscopes with a high class optics and construction, but they do not bear labels of famous brands resulting in higher prices. Delta Optical devices that we offer fall within this category of affordable microscopes.

The quality of optics in the microscope is usually first of all defined by the lens quality followed by the eyepiece quality. An achromatic object-glass is the standard of good quality. It helps correct image inaccuracies caused by light split when it passes the optical lenses. Even though an achromatic object-glass can meet the needs of many users. Whenever necessary you will achieve a higher image quality using an object-glass with semi-achromatic or plan-achromatic lenses. Plan object-glasses basically are “ideal lenses”, but they accordingly costs more.

There is a general rule when it comes to an eyepiece: the wider the field of view of the eyepiece, the better the device is. You should give preference to a device with a wide field (WF) or super wide field (SWF) eyepiece(s). However, you should bear in mind that the more you magnify the object, the less is the observation field.


Halogen lighting. In more general terms, this is a high quality, standard lighting. Halogen provides bright, white light and usually has rheostatic adjustment of light intensity.

LED lighting is becoming increasingly popular. If the manufacturer has provided the possibility of generating this lighting with help of batteries, a microscope becomes fully portable and can, therefore, be used comfortably at conferences or simply outdoors where there is no usual power source.

Fluorescent lighting. Such a light source is usually used in special cases during biological studies and for similar applications. Whenever more intense lighting is required, a fluorescent light is used as an additional source of light along with stereo microscopes.
