WebThe goal of microscopy is to create a magnified image of objects too small to be seen with the eye alone. Brightfield microscopes use a combination of glass lenses and light to view the specimen. Microscopes are often used to study bacteria, cells, and tissues. Fields of study where a Cytology cytology is study of cells Histology WebBright field microscopy is the simplest form of optical microscopy illumination techniques. The term is derived from the fact that the specimen appears darker in contrast to the bright background. Light from the illuminator is collected by the condenser and focused at the specimen mounted on the space.
