What is 'Herschel'? 'Herschel' (Herschel) is the largest telescope, launched beyond Earth. The diameter of its main mirror – one of the most important component of the optical system – is 3,5 meters. For comparison, the primary mirror 'Hubble' about a meter already – its diameter is 2.4 meters. The size of the primary mirror is directly dependent 'vigilance' telescope. Than it is wider, the more radiation can be collected. The diameter of the mirror – not the only thing that distinguishes 'Herschel' from 'Hubble'. Large telescope sees the universe not in the optical and infrared and submillimeter ranges.

All created so far infrared space telescopes of its size not even close to approaching the 'Herschel'. Their mirrors were collected on average 20 times less radiation than a mirror of the new telescope. Why do I need infrared? The human eye can not detect radiation in the infrared. Our vision is limited to a narrow wavelength range from 360 to 730 nanometers, called visible light. Watching came from the depths of the universe visible light, you can get a lot of information about stars, comets, and even some planets.

It Visible light is the primary source of information about space until the mid xx century. The idea of creating a huge orbital infrared telescope was born in 1982 at the European scientists. After 27 years of rocket Ariane-5 launched from spaceport in French Guiana. In the development of the telescope, 'responsible' for that is the European Space Agency, was attended by ten countries including the United States and Russia.

They also collaborated on companies like Internalia, ANEI, Fundetec and ARS sessions, to discuss the possibility of not to acquire applications and pay only for what is used, with the consequent cost saving for the company. The new Web and Econred, also intervened to encourage participation in the networked society and the great business opportunity posed by this activity to micro-enterprises in attendees. Google approached, as it could not be less, to the day, and in one of the most fresh interventions and with greater involvement of the seating capacity, resolved questions and inquiries of all types to attendees, offering a significant discount for all there present could test them the effectiveness of actions on this search engine. Finally, attended by 2 companies associated to AEMME which by its success and the use of new technologies are a clear example that it can also grow in these difficult times. Markarte, marketing and communication company with his presentation is the time for des-MARKARTE with ICT s told us that not only use technology to its management and internal development, but that they are an indispensable support for other companies begin to use them from the hand of experts from confidence at an affordable price. And as shows they offered also an online service to attendees so that they start to verify for themselves the advantages of being in the network at a very affordable price. Another participating microenterprises was BioBike, company that sells electronic bicycles and that with their showcase on the internet 24 hours a day, 365 days a year, get a traffic of visitors in your area about 800 a month remaining on your webpage for more than 5 minutes, somewhat unfeasible at the classroom level.

A special challenge for the Eschbacher engineers was an assembly-line production under vacuum with 10-6 mbar. It was necessary to integrate a fully automated Assembly of sandwich a beam with a precision slide and a rear counterpart into the production run. This must 1 m large foil with an accuracy of +/-20 m to the vehicle will be positioned. Because the position of the wearer vary, came only a positioning system with six degrees of freedom for the Assembly, which could not take more than 10 seconds, question. For the desired procedures by 50 mm in loading direction and 20 mm across it, a SpaceFab from Eschbach is recommended due to its low construction height. The system developed for this case can move without another load of 100 kg arm vibration, fast and very accurate.

A sophisticated combination of mechanics, pitch and high-resolution encoder provides the key. Developed to deliver the necessary dynamism also specifically for this application three-phase servomotors. Also a vacuum suitable for holding brake was redesigned as the solutions available on the market in terms of material properties and loss services not meet the requirements of this application. For the software to control the sandwich Assembly as well as the integration of the readings from sensors and cameras took over PI miCos the responsibility as well as for the monitoring of the gripper magnets. Thus, the medium-sized businesses proved that it quite projects is up to the requirements for complex multidisciplinary high-tech. 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. Offers for this PI miCos in addition to an extensive Standard range customer-specific system solutions with multiple axes of. 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 motors and air bearings.
