What is Microscope and how it works ?

The resolution (the level of image detailing) is the main difference between these two microscopes.

It uses lenses in order to magnify the objects so that it can be seen through the naked eye.

A microscope is of different types: Visible-light microscope [1] - Also known as optical or light microscope.

A compound microscope has two or more lenses. The eyepiece or ocular lens sits atop the body tube. Many microscopes are binocular and have two ocular lenses.

It uses visible light as the source and can be used to view objects as small as 0.2 microns.

There are two main types of light microscopes: COMPOUND and STEREO microscopes.

COMPOUND MICROSCOPES are so called because they are designed with a compound lens system.

The objective lens provides the primary magnification which is compounded (multiplied) by the ocular lens (eyepiece).

Answer and Explanation: The most important part of a microscope are the objective lenses.

The objective lenses are at the bottom of the microscope tube nearest the specimen; they gather and focus the light transmitted from the specimen.

Usually three or four objectives of different strengths will reside in a revolving turret, and magnification may be changed by turning the turret to line up a different lens with the body tube.

It is important to note that all of the parts of a microscope are important and without any single part a scientist will have much difficulty in observing his specimen.

Each part of the microscope has an important function.

Objective magnification strengths usually range from 10X to 100X. Fine and coarse focusing adjustments are accomplished with focusing knobs located on the body of the microscope.

A microscope is an optical device that is deployed to view highly magnified images of small things via a convex lens of small focal length with the purpose to analyse them accurately.

A Simple microscope utilises just a single lens for magnification. It is the fundamental design of the light microscope.

MICROSCOPE PARTS AND FUNCTIONS. Invented by a Dutch spectacle maker in the late 16th century, light microscopes use lenses and light to magnify images.

The resolution of a specimen is highly dependent upon the light waves. The shortest distance between two points that the microscope can define as clearly being separate points is the resolution of the microscope

Arm: Structural element that connects the head of the microscope to the base. Stage: The flat platform that supports the slides.

The microscopic world generally refers to things humans can't see with the naked eye. But thanks to microscopes, scientists have the tools to visualize the detailed structures and dynamic processes inside living cells.

The resolution is determined by the frequency of the light waves illuminating the specimen and the quality of the lens. A rule of optical physics is that the shorter the wave length the greater the resolution.

There are two main types of electron microscope: Scanning Electron Microscope (SEM) - A SEM sends a beam of focused electrons to the sample, which bounce off to create a three-dimensional surface image.

A simple microscope has one lens and is essentially a loupe or magnifying glass with a relatively high magnification.

Transmission Electron Microscope (TEM) - A TEM works by sending the beam of electrons through a very thin specimen.

Electron guns emit a flow of electrons of a considerably shorter wave length than visible light and this fact allows an electron microscope to have higher resolution and magnification.
