As we delve into this new series – a scientists’ toolkit, we start with the microscope. From its history through to its applications. Its uses are endless and we will show you why!
There are many different types, from light to electron, some are binocular others are not. There are digital, stereo, USB and pocket microscopes. Here are just a few of them below. Depending on the purpose different microscopes may be used, it is just about picking the right one for the job! (7)
Digital light microscope: invented in Japan in 1986. Uses principles of light microscopy, but connects to a computer similar to a printer/ Allowing for ease of observation. (7)
Stereo light microscope: Also known as a dissecting microscope, is used to view images three dimensionally by having 2 optical paths. (7)
Electron microscope: more powerful than a light microscope, and allows scientists to see things at nano size, there are two types; the scanning and transmission type. (7)
Microscopes are used by scientists for lots of different reasons- primarily to observes microscopic structures, and changes that cannot be seen by the naked eye. Allowing scientists to understand structure and physiology. This can help when trying to understand normal processes in the body, as well as changes due to disease, the effect of different therapies on the body, and possible therapeutic targets.
They can be used to visualize structures, conduct cell counts, diagnose disease and conduct qualitative scoring.
