    The electron microscope‚ instrument that produced the first magnified image showing ‘three-dimensional’ and highly magnified image of a small object. It directs a beam of electrons rather than light through a specimen. The beam of electrons is created from an electron gun. This beam then travels through the length of the microscope cylinder‚ which contains the lenses‚ the specimen chamber‚ and the image-recording system. Two types of electron lenses are used‚ electrostatic and electromagnetic

    2012 COMPOUND MICROSCOPE A compound microscope is an optical instrument used to see objects that are too small for the naked eye. A compound microscope is a microscope fitted with two or more convex lenses. The high magnification produced by these lenses together enables a detailed study of micro-organisms‚ cells and tissues. These types of microscopes are therefore widely used in scientific and medical research. The basic design of a compound light microscope consists of convex

    September 29‚ 2012 Introduction: The light microscope helps see the microscopic world that the naked eye cannot see. If there were no microscopes in the world‚ than it would be very difficult to understand the many particles that surround the living world. The purpose of this lab experiment is to become familiar with a microscope. It is hypothesized that it will be difficult to use the microscope without any previous training and that the parts and their function must

    An electron microscope is a type of microscope that produces an electronically-magnified image of a specimen for detailed observation. The electron microscope (EM) uses a particle beam of electrons to illuminate the specimen and create a magnified image of it. The microscope has a greater resolving power than a light-powered optical microscope‚ because it uses electrons that have wavelengths about 100‚000 times shorter than visible light (photons)‚ and can achieve magnifications of up to 1‚000‚000x

    Microscopes and Microscopy Introduction The purpose for including a lab on microscopy in his course is because it is a very important tool in making detailed observations. This lab helps the average person realize that there is much more to things than what you see with the naked eye. In the field of human biology microscopes are very important for many reasons. In the late 1500’s a scientist named Zacharias Janssen created the first microscope of it kind and now we have several microscopes

    Introduction Microscopes have brought to light a new realm of information that originally laid dormant and invisible to the naked eye. It has enhanced biology and brought forth great advancements into the study of living organisms. Many discoveries have been achieved through the microscope. One of the major ones is the cell theory that we have talked about in this chapter. Having a microscope enables us to study even the smallest of details in organisms and allows us to conduct research. Another
