Where was the microscope invented?
What are the advantages of microscope?
Microscopes help the scientists to study the microorganisms, the cells, the crystalline structures, and the molecular structures, They are one of the most important diagnostic tools when the doctors examine the tissue samples.
What are disadvantages of microscope?
The main disadvantages are cost, size, maintenance, researcher training and image artifacts resulting from specimen preparation. This type of microscope is a large, cumbersome, expensive piece of equipment, extremely sensitive to vibration and external magnetic fields.
What is the advantages and disadvantages of microscope?
Advantage: Light microscopes have high resolution. Electron microscopes are helpful in viewing surface details of a specimen. Disadvantage: Light microscopes can be used only in the presence of light and are costly. Electron microscopes uses short wavelength of electrons and hence have lower magnification.
Who uses microscope?
What Kind of Jobs Use Microscopes?

Do doctors use microscopes?
The cells that appeared under the microscope were epithelial cells, which line the surfaces of our organs and blood vessels. Doctors and clinicians still use medical microscopes to identify these types of cells, which can often tell us when something is going wrong in our bodies.
Do engineers use microscopes?
Engineers have relied on the optical microscope in order to discern surface features on fracture surfaces not readily visible to the naked eye. These surface features tell the history of how a particular object failed.
How do you carry a microscope?
Always carry the microscope with 2 hands—place one hand on the microscope arm and the other hand under the microscope base. Do not touch the objective lenses (i.e. the tips of the objectives). Keep the objectives in the scan position and keep the stage low when adding or removing slides.
Why should you never tilt a microscope?
Do not tilt the microscope or the eyepieces may fall off and be damaged. 2. Cleaning Wipe the stage after each use with absorbent paper. Use ONLY Lens paper to clean the eyepiece, objective lenses, and condenser lens.
How do you carry a microscope safely?

Why do you have to keep both eyes open when you look through the eyepiece?
If your eyes are too close set or far apart for the intraocular distance to be adjusted properly, you will have to use your microscope as a monocular instrument (i.e. look through one eyepiece with one eye). If you do this, it is important to keep both eyes open in order to avoid eyestrain.
