Take a closer look at your surroundings and get a brand-new perspective of the world with the aid of the right microscope. When it comes down to it, they are so much more than scientific instruments and can be a fun way to explore the environment around you in completely new ways. When choosing between these two most popular options, it helps to understand their key features, differences, and capabilities. There are many distinctions between a compound microscope and a stereo microscope, but most notable is how they work, their capability of magnification, and the imagery they produce to the human eye.
First invented in the late 16th century by Hans and Zacharias Janssen, a Dutch father and son team, the first so-called compound microscope was invented by discovering that if they put a lens at the top and bottom of a tube and looked through it, objects on the other end became magnified. Today, it uses two sets of lenses as well as multiple eyepieces and focal lengths to obtain higher levels of magnification.
A compound microscope provides a two-dimensional image with a magnification in the range of 40x to 1000x. They are used to view small samples, typically placed on a slide, that could never be identified or seen with the naked eye, revolutionizing our understanding of science and medicine. They come in a wide range of capability and price range, with beginner models starting off around $70 and professional-grade models coming in at up to $715.
These microscopes provide a high level of magnification that enables views at a cellular level. Most often, they do not require batteries and use power from an outlet to illuminate a single LED bulb. They also have the precision for a professional capability while remaining easy to use and understand for less experienced users. The head design allows for quick and easy changes to magnifications and the turning knob is adjustable to allow distance between the lens and the subject.
These microscopes are only capable of delivering a two-dimensional view, unlike the three-dimensional view provided by a stereomicroscope and they are not suitable for larger specimens such as rocks, jewelry, or larger objects. Also, they must be used on a perfectly flat surface to work properly and often require glass slides.

Horatio S. Greenough was an American biologist and instrument maker that developed the first stereo microscope in the early 1890s. The fundamental innovation that sets it apart from a compound microscope is its separate objective lenses and eyepieces that result in two separate optical paths for each eye. The slightly different angling views to the left and right eyes produce a three-dimensional visual, and because of this, it is also referred to as the dissecting microscope.
A stereo microscope today will provide a magnification of 10x to 40x and can handle larger items that don’t require a slide. Some can be connected to computers and LED screens to deliver larger amounts of data, information, and visual imagery. Many different options are available and they range in price from $80 to higher-end models being up to $700.
When using a stereo microscope, there is more room under the microscope for larger samples such as computer chips, flowers or woven fabrics. Slides are often not required, which means less fragile parts and accessories to purchase, store and transport. It also provides a three-dimensional view to see different angles and viewpoints of the observed specimens. Its viewfinder is positioned at a 45-degree angle for easy viewing with less neck strain.
Stereo microscopes often require a power source such as a plug-in outlet or battery. They do not provide as much magnification and are only suitable for larger specimens. You can’t see things at a cellular level with this type of microscope and it may be more difficult to store and transport. Stereo microscopes often aren’t as user-friendly and require some experience and getting used to.

When it comes to pure magnification, a compound microscope is the one to choose. A stereo microscope can be a fun device for home or classroom, but when it comes to usability and gaining a new perspective of the smaller worlds that exist around you, a compound microscope is a way to go.
