Video: Parts of a compound Microscope with Diagram Explained 1. An optical microscope (also known as a light microscope) refers to the variant of microscopes that involve the use of visible light rays and a lens system for magnified image formation of tiny objects. Most optical microscopes are compound microscopes, which means they contain at least two lenses. The condenser (containing the aperture diaphragm) and the luminous-field diaphragm normally contained in the stand base are the critical elements in achieving Köhler illumination. The eyepiece is positioned on the optical axis in such a way that its front focal point is on the intermediate image. The aerial intermediate image at O’ is further magnified by the microscope eyepiece (L ey) and produces an erect image of the object at O” on the retina, which appears inverted to the microscopist. Optical diagram of a microscope in the basic configuration. The eyepiece thus functions as a magnifying behind the objective. This section reviews the imaging and/or illuminating capability of these optical components and how they work together to … The objective forms a magnified, upside-down image, called “intermediate image”. Base: Bottom base of the microscope that houses the illumination & supports the compound microscope. Head (Body) The head, also referred to as the body of the microscope, is a structural component that contains the optical parts of the microscope. 4x, 10x, 40x, and 100x are the most common magnifying powers used for the objectives. In this diagram, fb represents the back focal length of the objective and z’ is the optical tube length of the microscope. What is an optical microscope? The optical microscope often referred to as the light microscope, is a type of microscope that uses visible light and a system of lenses to magnify images of small subjects. Lamp and Condenser project a parallel beam of light onto the sample for illumination ; Sample stage with X-Y movement sample is placed on the stage and different part of the sample can There are two basic types of optical microscopes: Simple microscopes; Compound microscopes. Optical microscopes, also called light microscopes, are the most commonly used type of microscope. Simple Microscope Definition Objective lenses : There are usually 3-5 optical lens objectives on a compound microscope each with different magnification levels. (a)Working of phase contrast microscope, (b) Line diagram of working od a fluorescent microscope & (c) Fluorescent treponent antibody absorption (FTA-ABS) for diagnosis of syphilis [6]. The figure below shows the area of the microscope considered to be the body of the microscope. Microscope Optical Components Interactive Tutorials Geometrical Construction of Ray Diagrams. Lenses are curved pieces of glass or plastic that bend rays of light and can magnify objects, making them appear bigger than they actually are. The sequence of components in the microscope optical train include the illuminator, condenser, specimen, objective, ocular, and camera or eye of the observer. The optical train and numerous other components of a modern microscope are presented in a cut-away diagram in Figure 2. A popular method of representing a train of propagating light waves involves the application of geometrical optics to determine the size and location of images formed by a lens or multi-lens system.
