Abstract
An optical combination of a photoreceptor and an optical fiber, in which a tip surface of the optical fiber and a photoreceiving surface of the photoreceptor is contacted to a surface of the spherical lens so that a light outgoing from the tip surface of the optical fiber into the spherical lens may be totally reflected repeatedly within the spherical lens so as to be incident on the photoreceiving surface of the photoreceptor, resulting in largely simplifying the optical positioning between the photoreceptor and the optical fiber without polishing the tip of the core of the optical fiber into a spherical or semispherical shape in an inexpensive manner.
