Abstract
A mold includes a cavity and a core which define a space in which an optical attenuator and supporting portion are formed. The includes a core pin, movably located in the core element. The core pin has a proximal end defining a surface of the lens portion and a distal end remote from the molding space. A core pin motor is coupled to the core pin, through a number of intermediate elements, so that the core pin can be moved relative to the core element to adjust a thickness of the lens portion. The intermediate elements can include a ball screw, a ball screw end cap fixed to a core pin holder block, a ball screw nut fixed to an outer surface of the mold so that an outer end of the ball screw passes through the nut to a location outside the mold.
