Abstract

A method for molding an optical attenuator having a unitary lens portion and supporting portion includes the steps of: providing a mold having cavity and core elements which together define a space in which the optical attenuator can be molded including a movable core pin having a proximal end defining a surface of the lens portion, and a core pin motor coupled to the core pin for adjusting the thickness of the lens portion; injecting a suitable polymer into the space to form the optical attenuator; separating the cavity and core elements to extract the optical attenuator from the mold; optically measuring the thickness of the lens portion; and providing a signal indicative of the thickness of the lens to a controller having an output coupled to the core pin motor, the controller providing a signal to the core pin motor specifying any movement necessary to retain the thickness of the lens portion within a desired range before repeating the injecting step.
