Abstract
An apparatus for aligning an optical element of an optical actuator. The optical actuator moves a guide between a retracted and an extended position relative to an actuator body. The actuator body has a channel, or through-opening, in which the mirror guide moves. In one embodiment, the channel has a two flat surfaces that form a portion of a v-groove in the channel. In the extended position, the guide contacts a stop pin, or stopper, and the two flat surfaces in the through-opening, thereby holding the guide in a position defined by the line of contact between the stop pin and an angled surface of the guide and a pair of parallel contact lines where the guide contacts the two flat surfaces in the through-opening.
Claims15
An apparatus for aligning an optical element in an optical actuator, said apparatus comprising:
- a driving mechanism for an optical switch actuator;
- a body attached to said driving mechanism, said body including a through-opening and a notch, said through-opening having a first sidewall and a second sidewall, said through-opening having a longitudinal axis;
- a stop pin positioned in said notch of said body, said stop pin being cylindrical, said stop pin fixed in said notch;
- and
- a guide for carrying the optical element, said guide movable between a retracted position and an extended position, said guide operatively connected to said driving mechanism, said guide having a cylindrical base and an angled surface, said stop pin having a longitudinal axis parallel to a plane defined by said angled surface, said guide having a longitudinal axis parallel to said longitudinal axis of said through-opening, said through-opening slideably receiving said guide, said guide contacting said first sidewall and said second sidewall when said guide is in said extended position, said angled surface of said guide contacting said stop pin when said guide is in said extended position.
