Abstract
PURPOSE:To ease conditions in production by connecting a rod lens of which the coefft. of refractive index distribution is smaller than 2 and the lens of which said coefft. is larger than 2 in a lengthwise direction thereby making sucn one rod lens of which the coefft. of refractive index distribution becomes 2. CONSTITUTION:Now it is assumed that a rod lens 11 of which the coefft. alpha of refractive index distribution is alpha 1.7 and a rod lens 12 of alpha 2.3 are prepared. If both rod lenses 11, 12 are connected in a lengthwise direction by means of an adhesive agent, the coefft. alpha of refractive index distribution is alpha=2 with the combined rod lens 2, and the coefficients alpha are equivalently offset and assume 2 which is an optimum value. The use of materials of which are coefft. alpha of refractive index distribution is alpha>2 or alpha<2 is made possible by doing in this way.
