The microscope is one of the principal tools of the scientist. Because objects can be very small, a microscope is often used to view them. Without the microscope, many of the great discoveries of science would never have been made. Microscopes were invented during the late 1600's and by the end of the 1700's had undergone dramatic improvements in their construction and the quality of the images they produced. The use of microscopes opened a whole new world previously unseen. It is important to remember that a microscope is a delicate instrument and that its proper care and use are quite essential to make meaningful observations as well as prolong the useful life of an expensive piece of equipment. The ability to magnify specimens has been around since 1000 B.C. It was the invention and modification of the microscope that changed the way scientists studied living organisms. It allowed scientists to study the structure of a living organism and to discover numerous species that were not visible to the eye. Today there are numerous types of microscopes available to scientists that provide greater magnification and resolution. Besides magnifying and resolving an object, the microscope also provides the contrast that is needed to distinguish detail, Microscopes can magnify up to 100X. The light is transmitted through the specimen on the stage and through two lenses before it reaches the eye of a person.
