Microscopes and Microscopy Essays Microscopes and Microscopy Paper Microscopes and Microscopy Paper A microscope, whether simple (one lens) or compound (multiple lenses), is an instrument that magnifies an image and allows visualization of greater detail than is possible with the unaided eye.   The simplest microscope is a magnifying glass or a pair of reading glasses. Microscopes are used for research wherein it commonly has a number of refinements to enable a complete study of the specimen. Because the image of a specimen is highly magnified and inverted, manipulating the specimen by hand is very difficult. As a result, the stages of high-powered research microscopes are mounted so that they can be moved by means of micrometer screws; in some microscopes, the stage can also be rotated. In addition, all research microscopes are equipped with three or more objectives, mounted on a revolving head, so that the magnifying power of the microscope can be varied. Discussion: The letter ‘e’ was inverted ‘  Ã‚   ‘.   The virtual image formed passed through a series of biconvex lens.   As the light pass through the lens, the image is inverted so as it appears and seen by the observer. The threads were ordered as red, green to yellow from top to bottom.   All magnifications gave a bit of idea regarding the orientation of the thread but 100x mag gave the best visual representation of the image being magnified.   Four hundred (400X) times magnification on the other hand revealed the specific detail details of the image being magnified.   The depth of field has affected the resolution of the image while objects situated at the top tend to appear blurred as compared to the image at the bottom. The interpupilary distance is adjusted towards or away from the eyepiece diopter.   Bring the sample very close to focus using the microscope focus slider while observing the image formed in the left eyepiece.   Utilize the left eyepiece diopter slider to bring the sample into sharp focus when the specimen approaches focus.   Using the right eyepiece diopter slider focus the specimen matching the left eyepiece. It is best to use the scanning or low power objective to have an overall view of the specimen and help the observer decide to which part of the specimen he will focus and bring to a higher magnification.   Shifting to a higher objective after locating the area of interest is done by turning the revolving nosepiece to the plane at which a higher objective is aligned at along the path of light.   The resolution and location of the specified are not very much changed due to the parfocal and parcentral features of the modern microscope. In bright field microscopy as you increase the magnification, you will also need to increase the amount of light necessary to see the object.   Therefore reducing the iris diaphragm aperture at high magnification may bring about distortion on to the image being magnified.   It is always that the smallest amount of light possible is used to view the object clearly. She could try to adjust the iris diaphragm aperture to increase the amount of light passing through the specimen.   She could also try adjusting the sub stage to increase the distance between the specimen and the source of light.   Increasing the distance between lenses increases the magnification therefore requiring higher light intensity to produce better magnification and resolution.
