ABSTRACT:
An optical fiber type part for optical systems which comprises a smaller number of parts, whose production does not require a long time and which has stable optical characteristics is herein provided. The optical fiber type part for optical systems comprises an optical element 9, first and second lenses and each arranged on the light-incident or light-outgoing side of the optical part and first and second optical fibers and each arranged on the light-incident side of the first lens and the light-outgoing side of the second lens respectively and is characterized in that the end faces of the first and second optical fibers which are opposed to one another are inclined at an angle and subjected to abrasive finishing and that anti-reflection films are formed on these end faces.
