An inexpensive fluorescent object is provided which may be used, for example, as a test object for color adjustment of a fluorescent endoscope system. The fluorescent object generates fluorescence while minimizing the generation of 'noise' at undesired wavelengths, and is made using a plastic that substantially does not deteriorate upon exposure to U.V. and visible radiation. A method of producing the fluorescent object is disclosed, namely, a plastic powder (such as PTFE) and an inorganic fluorescent powder (such as Mn-doped ZnS) are blended so as to form a mixture of these components, and the mixture is then molded by applying pressure to the mixture. An important feature of the invention is that heat is not added during any phase in the production of the fluorescent object, thereby preventing the inorganic fluorescent powder from being denatured when producing the fluorescent object.
