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 to see objects too small for the naked eye
