Claim Text:
1. An actuator comprising: a fixed support; and a movable member, the movable member mechanically coupled to the fixed support via at least two torsion bars, the movable member comprising: a support frame configured to oscillate about a first oscillation axis, the support frame comprising: a coil disposed between the first set of cut-out portions on the support frame and an edge of the support frame, at least a portion of the coil to be parallel to the first set of cut-out portions to reduce stress on the coil as the support frame oscillates about the first oscillation axis, the coil to conduct current to apply a Lorentz force to the support frame to oscillate the support frame about the first oscillation axis; a magnetic actuator to generate a magnetic field, the magnetic field to encompass at least part of the coil; and one or more boundary portions, each of the one or more boundary portions defined by second cut-out portions provided between the first set of cut-out portions on the support frame and the mirror to reduce an influence of warp transmitted from an edge of the support frame to the mirror as the support frame oscillates about the first oscillation axis.
