High Speed and High Precision Nanometric Positioner
- Summary
- Using the patented FELA (Flexural-based Electromagnetic Linear Actuator), we have designed and developed a high precision 3-axis nanopositioner that has a working range of up to 5mm. With a mechatronics design approach in mind, the stiff design was generated using a genetic algorithm to achieve an optimized performance specifications. Together with the control electronics analysis, whereby the actuator?s intrinsic capabilities can also be manipulated; we are able to achieve a high bandwidth control performance of up to 10Hz, which is significantly better than the nanopositioner currently in the market. The qualitative performance of the system is validated using our in-house calibration capabilities such as the laser interferometer, the laser Doppler vibrometer and the thermal scanner to measure the accuracy, vibrational disturbances generated and thermal distortion respectively.
- Technology Benefits
- Higher throughput Better reliability/yield Configurable in multiple axis (up to 3 axis in a single unit, and up to 6 axis as a system) Dynamic performances can be design and customized to customer requirements
- Technology Application
- It is suitable for all ultra-precision positioner, whereby a stringent accuracy yet high speed performance is required. Typical applications include precision alignment, optical setup in the electronics and semiconductor industries.
