OptoSigma Corp. is an international brand registered by the Japanese SIGMA KOKI group. The private company is based in Santa Ana, CA. The company specializes in vacuum-compatible piezomotor actuators that provide high-resolution incremental movement. The motion of these actuators relies on the structured, high-speed vibration of a piezo stack along with the force difference between the friction of a moving object vs. friction of a non-moving object. OptoSigma's PDM piezo actuators are available in two travel ranges and have industry-standard mounting interfaces, making them convenient drop-in replacements for standard micrometers. The company also offers customized piezomotor actuators to meet unique requirements.
