  • Compact piezoelectric inertial drive stage
    Patent number: 11606045
    Abstract: Disclosed is a piezoelectric inertial drive stage including a piezoelectric inertial driver, a slider and a holder. The driver includes a mounting portion for the mounting on the holder, a friction portion coupling to the slider, a flexure portion between the mounting portion and friction portion, a piezoelectric element with a first end bonded to the mounting portion and a second end bonded to a movement portion, the movement portion transferring the motion of the piezoelectric element to the friction portion to drive the slider.
    Type: Grant
    Filed: November 17, 2020
    Date of Patent: March 14, 2023
    Assignee: Thorlabs, Inc.
    Inventors: Renlong Gao, Guocheng Xu, Guobiao Wu
