Programmable Shims and Hybrid Actuators - Learn how they work. PIRest Active Shims - Nanometer Precise Programmable Spacers for Optics and Precision Engineering. These piezo shims can be programmed to change length. They do not require a connection to a power supply once programmed and are long term stable to nanometers.
