The eyepiece, or ocular, magnifies the primary image produced by the objective
Eye can then use the full resolution capability of the objective. The microscope produces a virtual image of the specimen at the point of most distinct vision.
A light microscope uses focused light and lenses to magnify a specimen, usually a cell. A light microscope is much like a telescope, except that instead of the object being very large and far, it is very small and very close to the lens.
In a modern microscope it consists of a light source, such as an electric lamp or a light-emitting diode, and a lens system forming the condenser.
The condenser is placed below the stage and concentrates the light, providing bright, uniform illumination in the region of the object under observation.
The most important imaging component in the optical microscope is the objective, complex multi-lens assembly that focuses light waves originating from the specimen and forms an intermediate image that is subsequently magnified by the eyepieces.
The objective lens of a microscope is the one at the bottom near the sample it is a very high-powered magnifyimg glass , with very short focal length .
This is brought very close to the specimen being examined so that the light from the specimen comes to a focus inside the microscope tube.
The objective itself is usually a cylinder containing one or more lenses that are typically made of glass, its function is to collect light from the sample.
Microscopes are an instrument that allows us to look more closely at objects.
It is used to magnify small objects.
Some microscopes can even be used to observe an object at the cellular level, allowing scientists to see the shape of a cell, its nucleus, mitochondria and organelles.
It can be used to cure diseases, and create new materials.
Some of their uses are tissue analysis, the examination of forensic evidence, to determine the health of the ecosystem, studying the role of protein within the cell, and the study of atomic structure.
