发明名称 ASPHERICAL ROD LENS AND ITS MANUFACTURING METHOD
摘要 PROBLEM TO BE SOLVED: To solve a problem that the coupling efficiency of optical coupling form is lowered and it is difficult to align an optical functional device in the case of assembling it because an optical coupling lens capable of realizing excellent collimated beams and a condensed beam at low cost can not be provided. SOLUTION: This aspherical rod lens 12 converting light radiated from a specified light source or the radiation terminal of an optical fiber 11 into specified light is equipped with a 1st surface 12a with which the light source or the radiation terminal is brought into contact and which has spherical or plane shape, and a 2nd surface 12b which is substantially opposed to the 1st surface 12a and which has aspherical shape by which the radiated light from the light source or the optical fiber is converted into the collimated beams and transmitted.
