Microscope
1) Simple Microscope
2) Compound Microscope
Aim: To study the different part of compound microscope.
Theory: A Microscope is used to observe microorganisms and analyze the structural details of cells as a fundamental tool. High-tech microscopes including phase contrast, dark field, and electron microscopes also are accessible, but simple and compound microscopes are still used in routine microbiology research. A simple microscope consists of a hand lens and magnifying glasses with a low magnification capacity. A mixture of lenses is used as the objective lens and the ocular lens in components to achieve higher magnification strength. The components are classified into two parts:
The first is structural component and another one is optical component.
1) A microscope is a device that magnifies images of the small object, which enable the onlooker to examine minute the structures at a scale suitable for observation and research. Although this study focused on optical microscopes, an image may be magnified using audiol, X-ray, or electrical current waves and obtained utilizing specific or optical imaging, or a combination of methods.
2) Structural components: there are three type of structural component of microscope. They are head, arm, and base. In the upper part of the microscope, the optical components are contained in the head. It is supported by the foundation, which also contains the eliminator (condenser). The arm has coarse and fine adjustment knobs, which make it easier to use the microscope.
3) Optical components:
a) Eye piece: A cylinder of two or more lenses is called an eye piece or ocular. Its role is to concentrate the picture for the eyes. 2x, 10x, and 50x are typical magnifications for the ocular lens.
b) Objective lens: The objective lens is normally a cylinder with a lens fixed to the circular disc with the microscope's movable head. The objective lens magnification ranges from 10x to 100x. The item has three or four objective lenses mounted to it.
c) Stage: The flat platform on which the slide is put is known as the point. A light eliminator is mounted underneath the stage to ensure that enough light gets via the gaps on the stage to concentrate the contents of the slide.
d) Condenser: Its role is to absorb light from a light source.
Working: The objective lens is positioned close to the viewing object, while the ocular lens is placed over the eyes. The objective lens is responsible for the object's primary enlargement. The picture is then transmitted to the ocular, where it is enlarged to its final size. As a result, the compound microscope's magnifying capabilities are determined by the objective's magnification and the ocular lens' magnification. For example, a magnification of 400x can be achieved by using a 40x objective lens and a 10x ocular lens. The objective lens produces a true and reversed image as its primary image.
