Abstract

In this study, we fabricated Al mirror driven by electromagnetic force. Because the mirror has Ni staple joint, it reduces the deflection angle of torsion spring for the maximum deflection of mirror. Therefore the magnetic field for maximum deflection can be reduced, By additional electrostatic force, the deflection angle of mirror plate can be increased to $90^{\circ}$. The fabricated mirror is actuated by electromagnetic force of a simple solenoid. The maximum deflection angle by magnetic field is about $86^{\circ}$ with $1.2{\times}10^4$ A/m.
