ABSTRACT:
In a packaging means for packaging together a light source or detecting means, a lens, and an optical fiber there is provided a sleeve for holding the light source/detector at one end of the sleeve and the lens at the other end to form a lens package. To hold the lens package there is provided a housing having first and second cavities opening onto each other and separated by shoulder means. The optical fiber is positioned in the first cavity with its end just short of the shoulder means. The lens package is retained in the second cavity with the lens abutted against said shoulder means with its focal axis aligned with the axis of the optical fiber and further with the tolerance error of the distance between said lens and the end of the optical fiber being determined largely by the variations in radius of said lens and variations in the position of the end of the optical fiber. The lens package can be retained in the second cavity by a matrix of flexible plastic partitions extending into the second cavity from the shoulder means in a box-like configuration which frictionally grips the lens package in an aligned position with the optical fiber.
