Cover microscope with dust cover and return microscope to storage if so requested. If you are interested in getting a close up view of the world around you, a light microscope could be the right choice. Light microscopes, which employ compound lenses and light, are commonly used in schools and homes. They work by using two lenses: an objective lens close to the specimen being viewed and an ocular lens or eyepiece. Understanding the proper care and use of the microscope can help ensure years of use.
