History of the Microscope

Microscopes have been around for the ages. Roman philosophers had mentioned "burning glass" within their works. However, the first microscope of this type was not invented until the 1300's. Two lenses were set on opposite sides of the tube. This tube of magnifying power was the basis for our modern-day microscope.

Oil Immersion technique, objectives, Resolving Power, Used for, Types.

What is Oil Immersion? Oil immersion is a technique, used to increase the resolving power or microscopic resolution of a light microscope. This is done by immersing the objective lens and specimen into a transparent oil containing a high refractive index, as a result, it increases the numerical aperture of the objective lens. The immersion

Confocal Microscope Principle, Uses, Parts, Advantages, and Disadvantages.

A traditional simple microscope creates a murky and fuzzy image of 3-dimensional objects, because light from all areas of the object, not just the plane of focus, enters the microscope. This problem has been solved by the confocal scanning laser microscope (CSLM), or simply, confocal microscope. Confocal Microscope Confocal Microscope also called confocal laser scanning
