Polytec's UHF-120 vibrometer wins the 2011 industry prize

The award is sponsored by the Huber Verlag für neue Medien (Huber Publishing House for New Media) and was judged by a panel of professors and trade press experts according to the level of innovation and future potential of the products.

The UHF-120 captures high-frequency vibrations and transient motion processes according to the principle of optical Doppler interferometry. The instrument can be applied to completely new applications due to its ability to measure frequencies up to 1.2 GHz (50 times higher than conventional vibrometers).

The UHF-120 provides direct optical measurement and subsequent motion visualization of novel microelectromechanical and microelectronic devices, such as RF-MEMS (as used in mobile phones), NEMS, ultrasonic transducers (as used in medical devices), or SAW and BAW filters.

The visualization method is comparable to a camera, capable of resolving minute vibration amplitudes of less than 1 pm, and ultra-high-frequency motions of up to 1.2 GHz. With the UHF-120, development engineers now can characterize the mechanical properties of a new device easily and precisely, leading to better products and shorter development cycles.
