This solar microscope consists of two main parts: the light housing and the body-tube. The light housing is composed of a frame on which an adjustable mirror is hinged and a tube containing a condenser to concentrate the light on the specimen. In the light housing is inserted a second tube made of cardboard covered in decorated paper, with a wooden mount. Screwed into this is a wooden cylindrical body with the stage and projection lens. The instrument, housed in a wooden box (lid missing), is signed by Isidoro Gaspare Bazzanti, about whom no information is known.
