cabinet. There are 3 main parts of the microscope such as illuminating parts‚ magnifying parts and mechanical parts. The sub-parts in illuminating parts are electric lamp and iris diaphragm while the sub-parts of magnifying parts are eyepiece and objective lens. The mechanical parts consist of most sub-parts among these three such as barrel‚ arm‚ stage‚ coarse focus knob‚ fine focus knob and base. Figure 1 : Fully Assembled Optical Microscope

resulting in an image that your naked eye would ordinarily see if looking at the slide. The image is then magnified by the lower (objective) lens. The objective lens flips the image and magnifies it by bending the light. The light is bent as it passes through the convex surface on either side of the lens material. The eyepiece acts as a weaker version of the objective lens by flipping the image again and magnifying it further. Compound microscopes are used most commonly

Lab Title: Microscopy Objective: To learn how to use and care for a microscope and to know the parts of a compound microscope and to efficiently use the microscope to focus on specimen. Introduction A microscope is an optical instrument used for viewing very small objects‚ typically magnified several hundred times. It consist of different lenses such as: Scanning = 4X‚ Low power = 10X‚ High power = 40 or 43X‚ Oil Immersion = 100X. A microscope is an instrument
