ABSTRACT:
An optical fiber light source assembly is constructed by assembling a light emitting device, a condenser lens, and a ferrule receptacle means for receiving an optical fiber ferrule in a housing. The ferrule receptacle means is adjusted on its optical axis in relation to the housing and is then fixed to the housing. The ferrule receptacle is guided in the housing along a pair of engaged reference circumferences therebetween, and is moved back and forth through a screw connection while being turned. After a reference front end position of an inserted ferrule is made coincident with the image point of the light source, the ferrule receptacle means is fixed in the housing using fixing means. An adjusting instrument is used to adjust the position of the ferrule receptacle means in relation to the housing.
