PPT-The Compound Microscope 2

nd stage Physiology Lab1 Pharmacology and toxicology department December 2020 Background Information The microscope is one of the most commonly used instruments in the medical colleges and in clinical laboratories Students of physiology use it in the study of morphology of blood cells and in counting their numbers . This model comes with color corrected infinity optical system (CSIS), a movable large working distance condenser, 45 degree inclined trinocular head, high eye-point Plan eyepieces, infinity long working distance PLAN achromatic objectives and infinity long working distance PLAN phase contrast objectives. This microscope offers nine brightfield magnification powers, 40X, 60X, 100X, 150X, 200X, 300X, 400X, 600X & 900X, and six phase contrast settings, 100X, 150X, 200X, 300X, 400X & 600X. Its 30 watt adopt Kohler illumination system was designed for 90-240V wide voltage power supplies. Care. Parts. Focusing. Types of Microscopes. Compound Light . Microscope - .  the models found in most schools, use compound lenses to magnify objects. The lenses bend or refract light to make the object beneath them appear closer.. From its humble beginnings the microscope has undergone numerous revisions since Leeuwenhoek’s day. But its usefulness has certainly not diminished. Numerous types of Microscopes are currently being used. Visit the following for a more detailed description of them. . Instrument used to make very small objects appear larger. Resolution. .  how clear an image is. . Magnification.  how much larger an object appears. Field of view .  area that you see through the lens. Care. Parts. Focusing. Types of Microscopes. Light Microscope - .  the models found in most schools, use compound lenses to magnify objects. The lenses bend or refract light to make the object beneath them appear closer.. http://biology.unm.edu/ccouncil/Biology_203/Summaries/Microscopes.htm. 1. When moving your microscope, always carry it with both hands. Grasp the arm with one hand and place the other hand under the base for support.. How to Focus on Specimen. Turn on light source on high. Turn the objective to low (4x). Lower the objective lens so that it is close but not touching the slide. Center the image by moving the stage. Adjust the diaphragm for optimum light. Light Microscope. Simple – uses a single lens. Compound – uses a set of lenses or lens systems. Simple Light Microscope. Compound Microscope. Mechanical Parts. Used to support and adjust the parts. Light Microscope. Simple – uses a single lens. . Compound – uses a set of lenses or lens systems (this is the type of microscope we use in class, it has the eyepiece lens (ocular) and the objective lens). - .  the models found in most schools, use compound lenses to magnify objects.
