Abstract

PURPOSE: To make possible multibranching of more than 3 branches, reduce the number of parts and made possible inexpensive production of small sizes by using a focusing lens wherein refractive index makes square distribution with respect to central axis and a reflection face is provided to part of the two meridian planes.
