Polytec manufactures a wide range of laser vibrometers that are the acknowledged gold-standard for non-contact vibration measurement. No matter your measurement need in research, development and production or even for long-term monitoring, there is a Polytec system to provide the answer. Laser-Doppler vibrometers analyze samples of different size, from entire car bodies, large aerospace parts over engines and actuators to micron-sized MEMS or delicate HDD components.

Numerous other research applications in mechanical and civil engineering, biology and medicine benefit from the superior properties of non-contact Vibrometry. Laser vibrometers easily master challenging conditions like measuring on hot surfaces, on rotating parts, and characterize complex and sensitive structures even in the ultrasonic frequency range. Vibrometers from Polytec help to solve your measurement task fast, reactionless and precise.

When producing strip material, e.g. in steel or paper mills, knowing exactly the strip length and the current velocity is essential for lowering your costs and optimizing your products and processes. Here, Polytec offers solutions for precise process control. LSV Laser Surface Velocimeters are high-performance non-contact sensors for a reliable measurement of length and speed.

Thanks to the optical measurement the sensor captures length and speed  reliably in challenging industrial environments. LSV offer a high level of robustness and process integrity at minimal maintenance cost.

In order to characterize precision-manufactured and other sophisticated surfaces, it needs measurement technology that is reliable, quick and application-oriented. Guaranteeing functionality and detecting defects at an early stage avoids unnecessary cost and increases the overall product quality and lifetime.

Polytec addresses surface metrology applications with innovative, high-precision, non-contact optical technology that works on rough, smooth and stepped surfaces. White-light interferometers of the TopMap family are established quality inspection tools for the controls laboratory, in production environments or in-line.
