Ultra-High Vacuum optical encoders

There are many industrial processes where the presence of significant amounts of air or other gases would be detrimental to the finished product. These processes must take place in an environment evacuated to very challenging levels of residual pressure. Where these processes involve motion control, Ultra-High Vacuum (UHV) encoder systems are necessary.

Maintain clean high-vacuum environments and minimise outgassing

All products in Renishaw's range of UHV compatible encoders are designed for use in a variety of scientific, semiconductor and other advanced industrial applications with vacuum pressures to 10-10Torr.

The fundamental principles of operation are the same as those for our equivalent standard-atmosphere products, but the UHV variants are designed to eliminate unvented voids and are specially constructed from clean, vacuum-compatible materials and adhesives. The suitability of the products for use in UHV environments is qualified by an independent specialist test house, including a Residual Gas Analysis (RGA) spectrum test (available on request).

The range includes incremental and absolute, open optical encoders.

There are many high-quality encoder products on the market, but few are also compatible with vacuum applications. Renishaw's TONiC UHV encoder delivers both excellent performance and reliability, it is our best choice.
