Precision mechanisms are a class of machinery/instrumentation that often have micron scale features, or even larger components that have can range down to nanometer scale tolerances within surface, positioning, or motion. These systems have applications ranging from satellite technologies and particle accelerators to MEMS, and nanotechnology instrumentation. Our efforts include research, design, development, manufacturing and measurement of high accuracy components and systems. Some examples are X-Ray optics and metrology, X-Ray and electron microscopes, precision microscopes and large accelerator detectors. These systems are often cryogenic and installed in ultra high vacuum environments.
