What is a light microscope?

Invented by a Dutch spectacle maker in the late 16th century, light microscopes use lenses and light to magnify images. Although a magnifying glass technically qualifies as a simple light microscope, today’s high-power—or compound— microscopes use two sets of lenses to give users a much higher level of magnification, along with greater clarity. The first set of lenses are the oculars, or eyepieces, that the viewer looks into; the second set of lenses are the objectives, the lenses closest to the object (specimen). Before purchasing or using a microscope, it is important to know the functions of each part.

What is the structural element that connects the head of the microscope to the base?

Arm: Structural element that connects the head of the microscope to the base.

What are the different types of objective lenses?

Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. The most common ones are 4X (shortest lens), 10X, 40X and 100X (longest lens). The higher power objectives (starting from 40x) are spring loaded. Spring loaded objective lenses will retract if the objective lens hits a slide, preventing damage to both the lens and the slide. All quality microscopes have achromatic, parcentered, parfocal lenses. In addition, to get the greatest clarity at high levels of magnification, you will need a microscope with an Abbe condenser. Lenses are color coded and are interchangeable between microscopes if built to DIN standards.

What is a microscope used for?

So, what are microscopes? Microscopes are instruments that are used in science laboratories, to visualize very minute objects such as cells, microorganisms, giving a contrasting image, that is magnified. Microscopes are made up of lenses for magnification, each with their own magnification powers.

Why are microscopes important?

Their ability to function is because they have been constructed with special components that enable them to achieve high magnification levels . they can view very small specimens and distinguish their structural differences, for example, the view of animal and plant cells, viewing of microscopic bacterial cells.
