Alignment of optical components, lens positioning, and mask alignment in lithography systems.
(Piezoelectric Internal Remanent strain) are a specialized type of piezoelectric, or "active," shims that offer long-term stable, sub-micron, and even nanometer-level positioning. Unlike traditional piezo actuators that require constant electrical voltage to hold a specific position, PIRest actuators maintain their position even after the power supply is removed. pirest actuators
PIRest actuators address several limitations of traditional piezoelectric devices and mechanical shims. 1. Zero Power Consumption for Position Holding Alignment of optical components, lens positioning, and mask
Common in , piezo actuators control injector needles with extreme speed, allowing for multiple injection pulses per combustion cycle, improving efficiency and reducing emissions. PIRest technology utilizes the lower part of the
PIRest technology utilizes the lower part of the piezo hysteresis loop, specifically by controlling the of the piezo material.
