A microscope's primary function is to magnify small objects so they can be seen clearly with the naked eye. It does this by bending or refracting light that passes through a specimen, producing an image that appears much larger than the object's actual size.

Also, never try to force any mechanical parts to move. If something seems to be stuck, consult the instruction manual or contact a professional. One common error of novice users is forcing the stage too far and breaking the slide against the objective lens.

Illumination is key in any optical instrument. The light source or illuminator, located below the stage, is there to shed light on the specimen. This not only allows us to see the specimen but also forms the image that is then magnified by the lenses.

The microscope stage, located below the objective lenses, is where you place the specimen or slide being observed. The stage holds the specimen in place and some, called a mechanical stage, can be moved up and down to bring the sample closer to or further from the objective lens.

Understanding the structure and functionality of a microscope is not just intriguing, but it also helps users maintain the instrument and troubleshoot basic issues.

Microscopes are not just about magnification; they also resolve the image. Resolution is the microscope's ability to distinguish two points on a specimen as separate entities, ultimately determining the clarity of the image. We commonly think of this as focus.

A stereo microscope is special in that it produces a 3D image of the specimen. Learn more about these unique models, who invented them and how they work.

While modern technology has introduced more complex types of microscopes, like scanning electron microscopes or atomic force microscopes, the essential principle remains the same – magnify the small things to help us better understand the microscopic world around us.

The simplest focal length definition is a description of the distance between the center of a lens and the image sensor when the lens is focused at infinity.

In a compound microscope, light emissions from the illuminator pass through the specimen on the stage. This light then goes through the objective lens, which magnifies the image and sends it up through the body tube and the ocular lens for you to view.

At the top of the microscope, we find the eyepiece or ocular lens. This part of the microscope is where we place our eye to observe the magnified image. The eyepiece has its own magnification power, typically 10x.

The word microscope is derived from Greek micros (small) and skopeo (look at). Just like any microscope, the primary function of the scanning electron microscope (SEM) is to enlarge small features or objects otherwise invisible to human sight. It does that by way of using electron beam rather than light which is used to form images in optical light microscopes. The images are obtained by scanning an electron beam of high energy on the sample surface, hence the name scanning electron microscope. By virtue of its smaller wavelength, electrons are able to resolve finer features/details of materials to a much greater extent compared with optical light. A modern day SEM can magnify objects up to one million times their original size and can resolve features smaller than 1 nm in dimension. Similarly, electron beam interaction with the specimen emits x-rays with unique energy that can be detected to determine the composition of material under examination. The SEM is, therefore, a tool used for materials characterization that provides information about the surface or near surface structure, composition, and defects in bulk materials. It allows scientists to observe surfaces at submicron and nano-level to elaborate material properties. It has emerged as one of the most powerful and versatile instruments equally valuable to materials and life scientists working in wide-ranging industries.

Another crucial part of the microscope is the objective lens. Located at the other end of the body tube, the objective lens is much closer to the specimen being observed. There are sometimes three or four objective lenses on a rotating turret, each providing different magnification levels, ranging from 4x to 100x.
