    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…

    not appear in focus because the specimen is not equally proportioned, some parts might be smaller and/ or not as equally thick. In addition, the depth of the microscope is limited because you can only focus on one layer at a time. You would have to section off certain areas by using the fine focus knob in order to focus on each part of the whole specimen. Steps for Viewing Briefly give the steps you would follow to use your microscope that is unplugged to view a specimen under 400X…

  • Refraction In Physics

    When light from an object enters the objective lens the lens will gather the light and refract it near the back of the telescope where the light rays will converge to a point (The focal point) the point of using a convex lens instead of a concave lens is due to convex lenses being able to converge light this diminishes the size of the image so that the light can fit into the eyepiece and due to the light rays continuing to travel past the focal point any image viewed past the focal point…

  • Light And Objective Lens Essay

    depends on the amount of light collected by the objective lens. How much light can be collected corresponds to the area of the objective lens. So the bigger the objective lens, the more light can be collected. If you want to increase the light gathering power by 4, you can double the diameter of the lens. How bright the image is depends on how an image can spread over a big area of a lens.The bigger the area, the less bright an image, and the smaller the area, the brighter an image would be. In…

    main lens, the objective lens, which is a convex lens that are thicker in the middle than the edges for different refraction of light and goes at one end of the tube, and the eyepiece for viewing, on the opposite end, which is also a convex lens. Light moves from air to glass, which is more optically dense, and slows down and bends towards the normal, when light travels out of the lens, it speeds up and moves away from the normal. Convex lenses are also called converging lens because they…

  • The Importance Of The Kinetoscope

    When we discussed the Kinetoscope in class last Thursday, I was intrigued by the design of this invention, but could not fully make sense of how it functions just by looking at pictures of it. An interior view of the Kinetoscope shows film wrapped around a number of wheels below an eyepiece, leading through another series of wheels that create vertical parallel rows of film, and running back towards the eyepiece. Although the film appears to pass beneath the eyepiece located at the crown of the…

  • Inverted Fluorescence Essay

    An inverted fluorescence microscope is an inverted compound light microscope equipped with modules to internally separate the different wavelengths of light, and direct them to respective detection channels. Its main components include a light source, an objective, a filter cube and a detection unit, which can be an eyepiece or a camera (Fig.1). Filter cube is a component which separates a fluorescence microscope from a light microscope. It consists of one excitation filter, one emission filter…

  • Difference Between Prokaryotes And Eukaryotes

    In terms of being able to practically distinguish between these two branches of organism, as well as subsequent classes, a compound light microscope can be used. There is a big difference between what is theoretically known to be inside cells, and what can actually be seen under a light microscope. In fact, a light microscope can only capture larger cell components like the nucleus, chloroplasts, nucleoli, and vacuoles (Biology Department, 2015). This means that differentiating between organism…
