The compound microscope is an optical instrument that is used to increase or enlarge the images of objects and organisms not visible to the naked eye. The common optical microscope is made up of three systems:
The mechanical system is made up of a series of pieces in which the lenses that allow movement for focusing are installed.
The optical system comprises a set of lenses arranged in such a way that it produces the increase of the images that are observed through them.
The lighting system comprises the parts of the microscope that reflect, transmit and regulate the amount of light necessary to perform the observation through the microscope.
