<P> The objective lens of a microscope is the one at the bottom near the sample . At its simplest , it is a very high - powered magnifying glass , with very short focal length . This is brought very close to the specimen being examined so that the light from the specimen comes to a focus inside the microscope tube . The objective itself is usually a cylinder containing one or more lenses that are typically made of glass ; its function is to collect light from the sample . </P>
