    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, we multiplied the ocular lens (10x) by the power of the objective lens. The diaphragm lets a certain amount of light through to the specimen. The bigger the diaphragm hole the more light, and the smaller the diaphragm hole, the less light. The field of view is the…

    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…

    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…

    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…

    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.

    photocathode inside the microscope by UV laser pulses. These electron pulses are accelerated inside the microscope and incident on the sample under study together with visible laser pulses. The photon-electron coupling between the optical pulses and the electron pulses takes place when the energy-momentum conservation condition is satisfied (27, 28). This inelastic interaction leads to gain/loss of photon quanta via electron packets, which can be resolved in the electron energy spectrum…

    Cellular Theory & Microscopes Robert Hooke Robert Hooke was an English scientist credited most famously for the creation of Hooke’s Law (a principle of physics that states that the force needed to extend or compress a spring by some distance is proportional to that distance) in 1660 and the discovery of plant cells using a compound microscope in 1663. The compound microscope uses two or more lenses, which are connected by a hollow tube. The top lens (called the eyepiece) is the one that people…

    A light microscope works like a telescope using glass lenses to reflect light, which magnifies images which are naked to the human eye such as cells and dust. The lens closest to your eye is called the eyepiece lens. This usually has a magnification of x10. Objective lenses are lenses of several different strengths which magnify the image. The stage is the place where the microscopic slide sits. This is held in place by the clips. The light source (can be a mirror or a bulb) projects light onto…
