Non-contact vibration measurement

Polytec manufactures a wide range of laser vibrometers that are the acknowledged gold-standard for non-contact vibration measurement. No matter what your measurement needs are in research, development and production or even for long-term monitoring, there is a Polytec system that provides 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 biomedical specimen and components.

Numerous research applications in mechanical and civil engineering, biology and medicine benefit from testing and measuring with non-contact vibrometry. Polytec 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. Polytec laser vibration sensors help to solve your measurement task fast and precisely.
