Reflected light microscopy - WikiLectures

Optical or light microscopy involves passing visible light transmitted through or reflected from the sample through a single lens or multiple lenses to allow a magnified view of the sample. The resulting image can be detected directly by the eye, imaged on a photographic plate, or captured digitally. The single lens with its attachments, or the system of lenses and imaging equipment, along wi… WebA microscope that uses reflected light is also known as a petrographic microscope. It is used for high magnification observation of petrographic thin sections and rocks. The majority of the light used in petrographic microscopes is reflected light. The light passes through a series of lenses and filters to produce color contrast in the sample.
