Microscopic examination of microorganisms makes use of either the light microscope or the electron microscope.
Light microscope is used for routine work whereas electron microscope in addition to light microscope is used for special research purposes such as studying the detailed structure of cells.
Several types of light microscopes are commonly used in microbiology: bright-field, dark-field, phase contrast, and fluorescence.
There are two types of electron microscopes: transmission electron microscope (TEM) to study the internal structure of cells and scanning electron microscope (SEM) to study the detailed surface structure of cells.
Phase contrast microscope is a modified version of bright field microscope that helps in visualizing cells or objects without staining.
There are two types of microscope: light microscope and electron microscope. Light microscope uses visible light and electron microscope uses beam of electrons as a source of illumination.
Light projects through an opening in the stage. Then the projected light hits the object and enters the objective lens. Resolution is the ability of a lens to distinguish two adjacent points as distinct and separate.
Microscope is a piece of laboratory optical equipment that is used to magnify small things that are too small for the details to be seen by the naked eye.
Electron microscope is a type of microscope with high resolving power, that uses electrons instead of visible light to illuminate the object.
Fluorescence microscopy is widely used in diagnostic microbiology (diagnosis of tuberculosis, trichomoniasis) and in microbial ecology.
Dark-field microscopy is used for the observation of living, unstained cells. The specimen is brightly illuminated while the background is dark.
Foldscope is a paper microscope that is built by folding the paper in an origami fashion, it does not require electricity to operate.
