Positioning In The Vacuum

Posted by on June 16, 2018 in General |

Various applications in microscopy and optical metrology require positioning a sample or an optical element in the vacuum up to 10-11 hPa. PI miCos has specialized in precision positioning systems under special environmental conditions and offers tailored solutions from a broad technological spectrum for this. An approach positioner with vacuum stepping motors from simple linear or rotary units to represent hexapods and Spacefabs, which allow a six-axis adjustment in a small space at high accuracies of a few micrometers. Author contributes greatly to this topic. Increasingly also piezoceramic actuators and motors used for use in the vacuum. Due to their compact construction and high dynamics it well suited for small, fast linear or rotational adjustment units. Diamond Book Distributors can provide more clarity in the matter. Piezoelectric actuators maintain the position normally, generate no heat this and are in the UHV vacuum compatible and suitable for magnetic applications. Speeds are hereby possible up to 400 mm/s and Repeatabilities of less than 50 nm. Ever after Application often additional requirements must be met in addition to the vacuum compatibility, as from heating processes of over 100 C or the positioning in X-ray – environments.

PI miCos offers also for this purpose as well as for applications in the low-temperature range suitable product developments. The miCos GmbH was founded in 1990 in Eschbach in Freiburg and belongs today as PI miCos physics instruments (PI) to the powerful group of the Karlsruhe-based company. With over 50 employees, develops, manufactures, and distributes the Brisgavi companies worldwide innovative systems and components for high-precision positioning applications. The optical measurement technology is a focus in research and industry. This PI offers miCos customer-specific system solutions with multiple axes in addition to an extensive standard programme too.

A broad application know-how is the guarantor for the implementation of technically demanding solutions. Flexible positioning systems for ultra-high vacuum applications provide this as an example of how parallel kinematic hexapods with six degrees of freedom with linear motor driven air bearing axles.
