Abstract

PURPOSE:To decrease the number of adjustment axes for an optical path and to easily improve the precision of the optical axis of optical parts by providing a positioning groove in a positioning supporting body, and manufacturing the optical parts on the groove. CONSTITUTION:A fiber 2 and a rod lens 4 are coupled together in such an optically excellent way that their optical axes are aligned with less than several mum precision. The positioning groove (a) worked in the positioning supporting body 1 with high precision is utilized for positioning. The gap between the fiber 2 and lens 4 needs to be filled with an optical adhesive, and an adhesive runout groove (b) is formed to prevent the adhesive 5 from running out by capillarity.
