AOS News Volume 25 Number 1 2011Vacuum compatible Mini HexapodIn vacuum chambers, there is very littleinstallation space for applications. Sincethe object to be moved is not permanentlyaccessible, a flexible placement of the load(e.g. a sample) is particularly important.The new M-811.STV MiniatureHexapod from Physik Instrumente (PI)and available through Warsash Scientific,offers the perfect solution. Due to itscompact design, with a diameter of only130 mm and a height of 115 mm, theM-811.STV offers travel ranges of up to 35mm in the XY plane and of 13 mm in theZ direction. It is especially the large tiltingangles of 20° around the X and Y axis andup to 40° around the vertical axis that makethis Hexapod so versatile.The Mini-Hexapod reliably positionsloads of up to 5 kg and achieves velocitiesof up to 10 mm/s. Each individual struthas a positioning resolution of 40 nm;positioning can be done repeatably withaccuracies under 1 µm.Like all Hexapod models from PI, the Mini-Hexapod uses a powerful digital controllervia Ethernet. All positions are convenientlygiven in Cartesian coordinates.Parallel-kinematics systems have severaladvantages over stacked multi-axispositioners. All six actuators act on a jointplatform, which keeps the moved mass low.Moreover, there is no summation of thelateral runout and tilts of individual axes.The pivot point can be selected as desiredvia software commands and thus remainsindependent of the movement.Well-known for its high quality, PI hasbeen one of the leading players in theglobal market for precision positioningtechnology for many years. PI has beendeveloping and manufacturing standardand OEM products with piezo or motordrives for 40 years now.Automated UV-visible-NIR Spectroscopy of Microscopic Features with the 20/20 PV from CRAIC TechnologiesThe 20/20 PV microspectrophotometerallows you to image and measure spectra byabsorbance, reflectance, fluorescence andemission from the deep ultraviolet to thenear infrared of sub-micron sized samplefeatures...automatically.CRAIC Technologies, the world’sleading innovator of UV-visible-NIRmicrospectroscopy solutions, is proud tointroduce the automated version of itsflagship product: the 20/20 Perfect VisionUV-visible-NIR microspectrophotometer.Available exclusively in Australia & NewZealand from Warsash Scientific, thissystem is designed to be fully programmablewith touchscreen controls so that it canautomatically analyze microscopic sampleswith UV-visible-NIR spectroscopy andmicroscopy. Imaging and spectroscopicanalysis of samples can be done byabsorbance, reflectance and fluorescencefrom the deep UV to far into the nearinfrared. Applications are numerous andinclude contamination analysis of harddisk components, thin film measurementof semiconductors, microcolorimetry offlat panel displays and quality controlof pharmaceuticals. With multiplespectroscopic techniques, high resolutionUV, color and NIR microscale imaging andadvanced automation, the 20/20 PV is thecutting-edge micro-analysis tool for anylaboratory or manufacturing facility.The automated 20/20 PVmicrospectrophotometer integrates CRAICTechnologies’ advanced Lightbladesspectrophotometer technologies withcustom built UV-visible-NIR microscopeand powerful, easy-to-use software.Incorporating fully programmableautomation features, touchscreen controlsand advanced software control, this flexibleinstrument is designed to acquire datafrom microscopic samples by absorbance,reflectance or even emission spectroscopy.By including high-resolution digitalimaging, the user is also able to use theinstrument as an automated UV, color andNIR microscope. Sophisticated software,ranging from image analysis, spectralanalysis, film thickness determinationand even colorimetry are all available toenhance the capabilities of the automated20/20 PV microspectrophotometer.With high sensitivity, durable design, easeof-use,multiple imaging and spectroscopictechniques, automation and the experienceof CRAIC Technologies in microanalysis,the 20/20 PV is more than just a scientificinstrument – it is a solution to youranalytical challenges.For more information about the M-811.STV or any other positioning systems, contact WARSASH Scientific Pty Ltd at (02)9319 0122 or sales@warsash.com.au41
