New Polytec Microscope-based vibration and motion analyzers
11 June, 2006
For full-field vibration analysis on very small objects such as MEMS optical switches, Polytec has developed the MSV-400 Microscope Scanning Vibrometer, a successor of the awardwinning MSV-300. The laser beam, delivered through the optics of a standard microscope, can scan an object up to 320 x 240 μm with a lateral resolution of about 1 μm. The new MSV-400 is the ideal tool for research on structures that are too small for analyzing with the standard PSV-400 Scanning Vibrometer. Polytec's MSV-400 is the perfect instrument for a quick and accurate vibration and motion analysis of unpackaged MEMS devices. For waferlevel testing, the MSV-400 can easily be mounted onto manual or fully automated probestations.

09 June, 2006
Polytec, the leader in the design and manufacture of scanning laser vibrometers for experimental modal analysis, announces the newest application for the advanced PSV-400-3D. The Air Force Institute of Technology, Wright Patterson AFB, Ohio will utilize this 3-dimensional scanning vibrometer to measure vibration characteristics of Unmanned Aerial Vehicles and other intricate aerospace and vehicular structures. Polytec's first North American sale of this premier instrument to AFIT permits engineers to perform complete 3-D vector component analysis on complex structures.
Bosch research facilities use new Polytec PSV-400-3D scanning
08 June, 2006
The PSV-400-3D Scanning Vibrometer is Polytec's premier measurement system for macro structure characterization. It combines three PSV-400 Scanning Laser Vibrometer heads, allowing true non contact visualization of 3-D motion. Bosch is a leading manufacturer of high quality automotive parts. Corporate research and development labs in Gerlingen, Germany were the first to benefit from the unique advantages of Polytec's PSV-3D system. In February 2004, Bosch's European Center for Brake Development and Testing in Drancy, France installed a new PSV-400-3D. A third system was purchased in May 2004 for installation at Bosch Braking Systems USA.
Just point and scan
07 June, 2006
In Aerospace or Automotive vibration measurement applications typically large but also often fragile structures are involved where non-contact measurement techniques are a must. Polytec Laser Vibrometers are the optimum choice for such applications.
New laser-precise length and speed measurement
06 June, 2006
The compact and robust LSV-300 provides precise speed and length measurement data which are critical for cost controlling and process optimization in the continuous or quasi-continuous production of materials such as steel, aluminium, plastics, paper and cardboard. High precision, easy integration, reliability and high ROI are the key features of the new non-contact Polytec measurement system and make it the first choice in many application areas.
New compact optical vibration sensor
05 June, 2006
Polytec presents the new multipurpose OFV-534 Vibrometer Sensor Head for non-contact vibration measurement. The excellent optical sensitivity that Polytec vibrometers are famous for has been packed into an extremely compact, very versatile sensor head housing. Despite the amazingly small size of its housing, the sensor head is both a high performance vibrometer, and a video camera (optional) for online monitoring of the measurement. In addition, a microscope lens can be fitted directly onto the sensor head which makes it possible to measure vibration on microstructures.
