It can be divided under a microscope into two parts; The mechanical system and the optical system. The mechanical system is how the microscope is built and the parts where the lenses are installed. The optical system is the lens system and how they manage to amplify the image. The optical microscope generates an enlarged image using several lenses. The microscope is perhaps one of the world’s greatest inventions. It is an essential tool that is widely used by medical professionals and scientists to study objects that appear to be invisible to the naked eye. This is because, the smallest object visible to the human eye is less than micrometres. Microscopes have helped mankind study a.

A microscope (from the Ancient Greek: μικρός, mikrós, "small" and σκοπεῖν, skopeîn, "to look" or "see") is an instrument used to see objects that are too small to be seen by the naked eye. Microscopy is the science of investigating small objects and structures using such an instrument. Microscopic means invisible to the eye unless aided by a e experiments: Discovery of cells.   The word microscope is derived from the Greek words micro (small) and scope (look at), and that's what a microscope does. It allows users to look at things too small to be seen by the naked eye. Microscopes have been around since the late 's when the Author: Beverly Hernandez.

or light microscope (vs./ an electron microscope). The simplest optical microscope is the magnifying glass and is good to about ten times (10X) magnification. The compound microscope has two systems of lenses for greater magnification, 1) the ocular, or eyepiece lens that. Your question does not provide much information about how much you already know about microscopes. This attempt to answer is limited to optical microscopes; there are other kinds. First, there needs to be a light source. It used to be the sun or a.

The parts of a microscope work together in hospitals and in forensic labs, for scientists and students, bacteriologists and biologists so that they may view bacteria, plant and animal cells and tissues, and various microorganisms the world over. Compound microscopes have furthered medical research, helped to solve crimes, and they have repeatedly proven invaluable in unlocking the secrets of.
