Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
107 words
A connector for an optical fiber comprising a light transmissive body, a cavity in the body having an entrance for receiving an end of an optical fiber, an aspheric lens, and a holder in the cavity for axially aligning the fiber with the lens, characterized in that, the body is of one piece construction, the cavity and the holder and the lens are formed on an internal surface of the body with the lens being axially aligned with the holder and positioned between the holder and a light transmissive end of the body, and the holder and the lens are formed as one piece with the body.
Claim 2
Dependent Claim
107 words
A connector for an optical fiber comprising a light transmissive body, a cavity in the body having an entrance for receiving an end of an optical fiber, an aspheric lens, and a holder in the cavity for axially aligning the fiber with the lens, characterized in that, the body is of one piece construction, the cavity and the holder and the lens are formed on an internal surface of the body with the lens being axially aligned with the holder and positioned between the holder and a light transmissive end of the body, and the holder and the lens are formed as one piece with the body.
Claim 3
Dependent Claim
