Document Type and Number:
Japanese Patent JPS5818980
Kind Code:
A
Abstract:
PURPOSE:To make a bar-type lens of a high price as needless, and to obtain an optoelectric transducer generating no disorder of the lens system by a method wherein a receptacle having a cylindrical cave is used when an electro-optically transducing element and optical fiber are to be coupled on the same axis, the element and fiber are positioned respectively at both the end thereof, and a spherical lens to be fixed to a fixed ring is provided between them. CONSTITUTION:The cylindrical cave 12 is provided in the receptacle 11, optical fiber is arranged at the open end on one side thereof, and the electro-optically transducing element 15 is arranged at the open end on another side respectively. Namely, the ring 17 to be fixed is inserted being positioned at nearly the center part in the cave 12 and is fixed, and the spherical lens 16, a plane washer 19, and a spring 13 are arranged in order toward the element 15 side. Then the electro-optically transducing element 15 having radiating fin 22 is screwed in the cave 12 using thread grooves 20 provided on the outside circumferential end face of the cave 12 and on the inside circumferential end face of the radiating fin of the element 15, and the end face is made to come in contact with the spring 13.
