ABSTRACT:
An optical system includes an optical member made of a solid material being a mixture prepared by dispersing inorganic particles in a transparent medium. The transparent medium and the inorganic particles of the solid material, and the volume ratio of the inorganic particles to the transparent medium are set so that the optical system can appropriately correct aberrations such as chromatic aberrations.
