ABSTRACT:
Two types of structural elements each employable for a light diverging/converging device are disclosed. One is a double circuit diverging ferrule which comprises a first semicylindrical ferrule element, a second semicylindrical ferrule element and a cylindrical bushing through which both the ferrule elements are press-fitted. The other is a single circuit converging ferrule which comprises a first semicylindrical ferrule element, a second solid semicylindrical ferrule and a cylindrical bushing through which both the ferrule elements are press-fitted. Three types of light diverging/converging devices, i.e., a diverging ratio variable type 1.times.2 circuit light diverging/converging device, a diverging ratio variable type 2.times.2 circuit light diverging/converging device and a 1.times.2 circuit light diverging/converging device having a constant diverging ratio each of which is constructed by using the aforementioned structural elements are also disclosed. A 2.times.2 circuit diverging unit, a tree type light diverging/converging device and a star type light diverging/converging device are modified light diverging/converging devices. A method of producing each of the aforementioned structural elements is further disclosed.
