PPT-Use and Care of a Compound Light Microscope

Animal and Food Science Department Brigham Young University Idaho Introduction A microscope is a tool that allows us to view things that are to small to see with the naked eye The most common microscope is the compound light microscope. POLARISED LIGHT MICROSCOPE . Designed to observe optically anisotropic specimen (BIREFRINGENCE SPECIMEN). Equipped with POLARISER and ANALYZER . Works on the principle of INTERFERENCE . COMPONENTS OF POLARISED . CONCEPTS EXPLORED IN THIS LESSON. ocular lens / eyepiece. body tube. arm. base. light source/illuminato. r. revolving/rotating nosepiece. objective lenses. coarse adjustment knob. fine adjustment knob. 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. . Practical 1. OBJECTIVES. IDENTIFICATION OF THE VARIOUS PARTS OF THE MICROSCOPE. DEMONSTRATION OF THE PROPER METHODS OF: CARRYING, USING, AND PRESERVING THE MICROSCOPE. DEFINITION OF SOME COMMON TERMINOLOGIES. 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. - .  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..
