NEW MODULAR POLYTEC VIBROMETER PRODUCT LINE FOR NONCONTACT VIBRATION ANALYSIS
14 August 2003 - POLYTEC GMBH

With the new Vibrometer Controller OFV-5000 and (the also new) Vibrometer
Sensor Heads OFV-505 and OFV-503 Polytec once more sustains the leading
position in the field of non-contact vibration measurement. Polytec Laser Doppler Vibrometers are used to precisely measure mechanicalvibrations, quickly, easily and free from cross-talk or feedback problems. They operate on the Doppler principle, measuring back-scattered laser light from a vibrating structure, to determine its vibrational velocity and displacement. A vibrometer system is made up of a controller and non-contact standard optic or fiber optic sensor head.

The new OFV-5000 Controller is the core of Polytec's latest state-of-the-art laser
vibrometer systems. Its modular design allows the frequency, velocity and
displacement capabilities to be tailored to specific or multiple applications. Both
analogue and digital decoders are available, giving a frequency range from near
DC to 20 MHz, with velocities up to ± 10 m/s and displacements from the
subnanometer to meter range. Full remote control, laser auto-focusing and other
functions are incorporated, allowing the OFV-5000 to be incorporated as part of a
small scale lab test, or expanded all the way up to a full scanning vibrometer
system.

Standard optic single point sensor heads are used for applications in the
automotive, aviation and aerospace industries, on electrical appliances or
machines, for monitoring buildings, on-line quality testing and other mechanical
production, research and development projects.

The completely new optical design of the OFV-505 and OFV-503 single-point
sensor heads offers outstanding performance and reliability as well as
exceptional optical sensitivity. The OFV-505 features autofocus and focus
memory. Coupled to the new OFV-5000 modular vibrometer controller, the OFV-
505/503 sensor heads take full advantage of the higher resolution digital as well
as analog processing of the OFV-5000. OFV-505 and OFV-503 are at the heart
of a range of universal and expandable non-contact vibrometer systems.
