发明名称 OPTICAL FIBER COLLIMATOR
摘要 PURPOSE:To prevent the exfoliation of the adhered part occurring in the thermal expansion of a ferrule by using a material having the low coefft. of thermal expansion equiv. to the coefft. of thermal expansion of an optical fiber to form the part at the front end of the ferrule where the optical fiber passes. CONSTITUTION:The front end of the ferrule 10 is finished by polishing and a transparent spacer 30 is adhered by an optical adhesive material 40 to said front end. The size of the spacer 30 is so selected that the spacer 30 contacts only the ceramic part 12 of the ferrule 10. The ferrule 10 is inserted from the base end side of a sleeve 50 into the sleeve 50 and a spherical lens 60 is disposed to the front end of the sleeve 50. The ferrule 10 and a spherical lens 60 are adhered and fixed by an adhesive material 70 to the sleeve 50. The force to exfoliate the adhered part of the ceramic part 12 and the spacer 30 is not generated even if the metallic part 11 of the ferrule expands thermally in this case.
