Guided autofocus assembly

A buckler wire actuator assembly comprising:

• a first buckler frame mounted onto a first side of a base of the buckler wire actuator assembly and including:
• a first isolated conductor circuit, a second isolated conductor circuit, and a first insulator layer disposed between and electrically isolating the first isolated conductor circuit and the second isolated conductor circuit;
• a first SMA wire in electrical connection to a first isolated electrical conductor electrically connected to the first isolated conductor circuit at a first end of the first SMA wire;
• and
• a second SMA wire opposite the first SMA wire, the second SMA wire in electrical connection to the second isolated electrical conductor at a first end of the second SMA wire;
• a first pair of actuator arms that include a fixed end that are connected to the first isolated electrical conductor and the second isolated electrical conductor, respectively;
• and
• a second buckler frame mounted onto a second side of the base, the second buckler frame including:
• a third isolated conductor circuit, a fourth isolated conductor circuit, and a second insulator layer disposed between and electrically isolating the third isolated conductor circuit and the fourth isolated conductor circuit, a third isolated electrical conductor electrically connected to the third isolated conductor circuit, and a fourth isolated electrical conductor electrically connected to the fourth isolated conductor circuit;
• and
• a second pair of actuator arms that include a fixed end that are connected to the third isolated electrical conductor and the fourth isolated electrical conductor, respectively, wherein the first and second SMA wires are arranged in series to enable both the first and second SMA wires to receive equal current from a current input.
