Lab Five: Microscope and Simple Staining Introduction A microscope is a tool to examine enlarges image of small objects that are hard to study with the naked eyes. The light microscope, which was used in this lab experiment, is an instrument with two lenses and various knobs to focus the image. We will learn about the proper way to use and handle the microscope. Microorganisms are measured with an ocular micrometer, which is inserted into one of the microscope eyepiece. Micrometer serves as a scale or ruler, is flat circle of glass upon which are etched in equally spaced division. When placed in the eyepiece the line is superimposed may be calibrated by using a stage micrometer on which parallel lines are exactly 10um apart etched. By determining…

Introduction The microscope is an optical instrument that produces large images of small objects that cannot be observed by the human naked eye. There are two types of light microscopes: compound microscope and Electron microscope. Light microscopes are divided into two categories: Compound microscopes and Stereoscope microscopes. Electron microscope functions in the following way; a stream of electrons emitted from an electron source built in the microscope, the obtained image is in black and…

Discussion Microscope is an optical instrument that have magnifying lens which is used for inspecting objects that is too small to be seen or to be seen distinctly and in details by the unaided eye. Microscope also is an optical instrument that keep observe specimen in resolution and magnitude way. However, there are some microbes such as viruses that cannot be observe by certain microscope and this microbes has to be observe using electronic microscope which has more magnification power. In…

During the microscope lab, my partner and I learned how to properly use a microscope, calculate the field of view, and view and prepare slides. Microscopes are instruments used to view very small objects that cannot be seen with the naked eye. We found that microscopes have many different parts to them, including the diaphragm, ocular lens, and objective lenses. There are three powers of magnification, scanning power (4x), low power (10x), and high power (40x). To find the total magnification,…

Purpose: Observe a compound light microscope to learn the names of its major parts. Research: Microscope is an essential tool for the study of small structures such as cells. The most common type of microscope is the bright-field microscope, used for this purpose is the compound light microscope, it is called compound because it uses two sets of lenses the objective and the ocular. The ocular lens usually magnifies 10x. …

The first scanning electron microscope (SEM) was invented by Manfred von Ardenne in 1937 (McMullan). However, further development of the SEM was accomplished by Charles Oatley and his colleagues at Cambridge University (McMullan; Egerton 17). He and his colleagues acquired their first images from the SEM in 1951 (Egerton 17). The SEM was developed because if a TEM is utilized, a specimen must be made extremely thin to prevent the electrons from dispersing inside the specimen and so the electrons…

Electron microscope (Manning, n.d.) is the instrument used to magnify different scientific artifacts with the used of electron beams to create the illustration of the sample, and has the capacity to magnify two million times of the original specimen. The development of the electron microscope was first known in the year 1931 because Ernst Ruska and Maximoll Knoll magnified electron image successfully, but the equipment was actually constructed in 1933 (Innes, n.d.). The concept of the electron…

For what do we use microscopes? Do we need them for any types of jobs? Microscopes are very helpful for many jobs such as doctors, jewellers, Environmental and Geoscientists, Forensic Science Technicians, Biological scientists and many more. Microscopes help us see things that we are not able to see with the bare eye such as cells, bacteria and much more. For this essay I will be mainly focusing on how microscopes help doctors in their jobs. I will be talking about how microscopes have helped…

bacteria under the microscope with the resolutions 10x, 40x, and 100x with the use of immersion oil. Observations were noted and we replaced that yogurt slide with the prepared, stained yogurt slide. We compared and noted the observations between the two yogurt samples. Exercise 3: Preparing and Observing a Blood…

a 3D microscope different than those taken with a regular camera? How are they similar? The 3D microscope photographs are used to show detail that a regular photograph could not, for example at a crime scene. The similarity is the basic image, it is the same image but the only difference it has with a 3D microscope is the detail shown. 2. How can photography allow us to view the world around us in different ways? Photography captures not a second of the environment, but to capture a moment. We…
