Polytec manufactures a wide range of laser vibrometer, velocimetry and surface topography instruments and have been bringing light into the darkness of non-contact measurement for more than 50 years. We develop, produce and distribute optical measurement technology solutions for research and industry. Our quality innovative products have an excellent reputation internationally among the expert community. We find solutions tailored to our customers’ requirements on a day-to-day basis.
If your measurement need is in research, development, production or even for long-term monitoring, there is a Polytec system that will provide a non-contact solution. Our equipment range allows for analysis of different size, shape and material from entire car bodies, large aerospace parts or engines and actuators, to micron-sized MEMS or delicate HDD components.
Polytec solutions offer the ability to design right, first time, with non-contact measurements that can be correlated back to design solutions. Non-contact means zero mass-loading, so there is no influence on vibrational characteristics. The FE-like spatial data resolution or point density from our PSV systems allow modal analysis performance in higher modes allowing meaningful Modal Assurance Criterion Analysis. Simply import the measurement grid from your FE model into the Polytec software to use the identical coordinate system instead of interpolation. The virtually unlimited measurement points on your structure result in high spatial resolution, over conventional tactile methods such as accelerometers.
Polytec’s optical surface metrology range includes innovative, high-precision and non-contact tools. They are based on the principle of white-light interferometry, which is also known as coherent or vertical scanning interferometry or coherence radar. Thanks to their large field of view, vertical range and nanometre resolution, they are perfectly suited for contactless measurement to obtain flatness, step height and parallelism information of large surfaces and structures – on almost all materials.
