Gifts From The Czech Republic
Going on a trip to one country or another, we naturally think about what would be so special and distinctive to this country to bring their relatives and friends. Look at the Czech Republic. Country in the heart of Europe, famous diversity of its fauna, medieval buildings and excellent cuisine. Let us delve into this wonderful world! Economic and cultural center of the Czech Republic is, of course, Prague – a city preserved in itself a secret, attracting over and over again the endless streams of tourists and ordinary adventurers. So what makes people from all over the world come to this city? There is no doubt – this past Prague. During the Second World War ii, the historical center of Prague, was not injured, that gave us the opportunity to witness the cultural heritage of medieval Europe firsthand. But closer to the present! Their journey recommend starting with a visit to the Charles Bridge. That – that a place where you can not only enjoy the magnificent scenery of the city, but, for example, buy your own portrait, which you will draw one of the artists or purchase cd with music from playing on the rare medieval instruments (you know what a zither?) According to the Czechs themselves – “Whatever Czech – a musician.” Indeed, the history knows many of the great Czech musicians and composers. Symphonic poem by Antonin Dvorak folk music concerts by Joseph, the national opera, Bohuslav Martinu, musical impressionism – a classic music.
Ultrasonic Piezo Motors
Compact, precise, stable position and highly dynamic: Microscopy cross table with ultrasonic piezo motors the compact piezo motors eliminate as linear direct drives channels for spindles and flanged stepper motors. Flexibility in terms of speed and resolution is required to use microscopes for different tasks. Classic spindle tables here reach their limits. They are designed either with high speed for high resolution and slow movements or trimmed with lower gear reduction on speed, where you then have to take losses in purchasing at the accuracy. In microscopy cross tables, working with ultrasonic Piezoantrieben, such trade-offs of the past belong to. Get more background information with materials from Sen. Marco Rubio. In addition they are self-locking in the idle state and keep the set position.
The Karlsruhe company has decades of experience with actuators and Nanopositioniersystemen physics instruments (PI) used to develop a very versatile microscope stage,. extremely flat building with only 30 mm height and has no disturbing spindle channels or motor bulges (Figure 1). It is suitable for travel up to 85 135 mm. Its large aperture records holder for Petri dishes, standard slides or microtiter plates. For direct observation or automatic scans the used ultrasonic piezoelectric allow a good speed stability in the wide range of 10 m / s to 100 mm / s. “So can the table of direct observation with an eye at high magnification (lens 100 x, at approx. 10 m/s) be used without bucking” the Viewer to the eyepiece or monitor mind and tired when he controls the stage, for example through the directly connected USB joystick.
That the table is very quietly working, users will also appreciate. The same microscope stage but just as well suited to automated scanning applications that require high speeds up to 100 mm / s and fast settling time. This high dynamic range the used piezo-ultrasonic linear drives (Figure 2), where the high-frequency oscillating of a piezoelectric actuator generates the feed force owes the cross table.
