    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…

    which allows the light and the image to enter the eye. Generally, a bigger ocular lens means more light reaches your eyes, producing a brighter image. A large ocular lens also makes it easier to maintain a full image if your hands move or shake. The ocular lens diameter is calculated as the ratio between the objective lens and the magnification. For example, in a 7x35 pair of binoculars the ocular lens is 35 divided by 7 which equals 5mm. For most hunting applications an ocular lens of 4mm or…

    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…

    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…

    upright position not allowing the eyepiece to fall out. When placing the microscope down be sure to keep it at least 10 centimeters away from the edge of the table or desk, also have the arm of the microscope face you. When the microscope is in a safe place on the desk, look at the objectives on the microscope. These objectives are labeled by 10x and 40x. The “x” stands for times. So when it’s 10x that means it magnifies the object 10 times it’s normal size. Create a data table that includes the…

    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…

    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…
