Substage: The area under the stage, called the substage, may contain a diaphragm, a. condenser, or both. Diaphragm: The diaphragm regulates the amount of light passing from the light source. through the specimen and through the lens system of the microscope.
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.
