ABSTRACT:
A optical fiber alignment device with a collimating lens, includes a ferrule for receiving the optical fiber; a ball having an axial hole for receiving the ferrule; a housing having a socket in one end for receiving the ball; and a lens barrel in the opposite end for receiving a lens sleeve. A compression ring for urging the ball into the socket is forced by a first spring located to apply a compression force to the compression ring by an end cap. A channel in the housing allows for the introduction of a bonding agent to bond the ball in the socket to maintain a desired position after adjustment. A lens fixed in a lens sleeve is located in the lens tube at a position to collimate light exiting from the optical fiber. A second spring located between the lens sleeve and the lens barrel urges the lens sleeve out of the barrel and a channel in the housing is provided for introducing a bonding agent to bond the lens sleeve in the lens barrel to maintain the desired position.
