Before the advent of the microscope, we were faced with visual limitations. The microscope, much like its precursors the magnifying glass and glass lenses were created to help us to see smaller things that would otherwise be very difficult to see with the naked eyes.
Invented in the 1590s, the first microscope of sort was created by Hans and Zacharias Jansen. The innovators affixed lens of the ends of a tube and realised that using that contraption helped to make the objects larger. Doctor Giovanni Faber named the instrument. After that, it stared becoming quite popular, especially among scientists.
By the time the eighteenth century rolled around, the microscope had already gotten many upgrades and was now even more widely used in the field of science. The microscope maker Antoni van Leeuwenhoek is said to have increased the level of magnification in microscopes, which went a very far way in the discovery of bacteria and the life cycles of insects.
The 19th century bought with it, the construction of, among other things,
those slides to place the specimens that have already been examined on. Also developed, were the objective lens, and the development of those objective lenses that controls the magnification and resolution of each specimen.
Fritz Zernike created the phase-contrast microscope that is used to examine material that is transparent, colorless and organic. Then the electron microscope was created by Ernst Ruska. Gerd Binnig and Heinrich Rohrer developed the microscope that could scan and was used to view objects at the nuclear level.
Fast tract to this century, and the microscope is now everywhere and is capable of doing so much more. For instance, the ultra-microscope was created by Richard Zsigmondy. This super microscope aided him in observing objects below light’s wavelength.
There is also the compound microscope; a multi-purpose instrument. Its short focal length objective lens is used to form images that are significantly enlarged. This is the simplest microscope that is generally used by science students especially in school labs. It has two stages of magnification; the objective lens and the eyepiece. One special feature of the compound microscope is its ability to light the specimen so it can be better seen. There is also the digital microscope that comprises of a double view using a microscopic camera as well as digital camera which can send images to a computer screen. This type of microscope is extremely economical.
