Abstract
An apparatus and method for lens surfacing. The apparatus includes a voice coil, piezo stack and cutter connected by a connection mechanism and regulated by a hierarchical sliding mode control system. The invention allows for both coarse and fine movements of the cutter during surfacing.
Claims20
A dual-stage actuation system for high precision optical manufacturing, comprising:
- a connection mechanism for a dual-stage actuator cutting tool that minimizes displacement loss, and maximizes robustness of the actuator cutting system.
A control system for a dual-stage actuation cutter system, comprising:
- a hierarchical sliding mode control that is defined as the intersection of two hyper-planes, wherein the first hyper-plane is constructed using the partial stats of the system that correspond to the coarse motion, and the second is constructed using the partial states of the system that correspond to the fine motion.
A dual-stage servo actuator system for optical manufacturing, comprising a unitary tool that allows for both course and fine positioning, and
- a mechanism for smooth and effective operation of the dual-stage actuation tool.
A method of high precision optical manufacturing, comprising:
- utilizing a dual stage actuation system to minimize or eliminate lens fining and polishing from conventional lens processing.
A method of high precision optical manufacturing comprising:
- blocking a lens;
- machining the lens utilizing a dual-stage actuation system;
- cleaning and coating the lens.
