Polytec's latest technology is used for cutting edge applications in the field of Micro-Electro-Mechanical Structures (MEMS). Our Micro System Analyzer (MSA-500) combines powerful tools for analysis and visualization of structural vibrations of MEMS. (read more)

Digital vibrometer systems utilize the latest technologies for digital signal acquisition and processing. They are based on a purely numerical Doppler signal decoding technique, where displacement information is not recovered by analog demodulators but by powerful data processing algorithms. (read more)

COVIDIS is a high end length and velocity sensor that can measure with measurement errors of less than 0.05%. The COVIDIS sensor which works on the Spatial Frequency Filtering concept, can help save thousands, by minimizing the wastage of raw materials. (read more)

Polytec Laser Doppler Vibrometers are precision tools for non-contact vibration measurement. Designed to be quick, easy to operate and free from cross-talk or feedback problems, these instruments determine a structure's velocity and displacement from the Doppler shift of back-scattered laser light.
