Polytec

Polytec is a German manufacturer and technology leader in optical measurement systems, best known for its laser Doppler vibrometers (LDV) and laser surface velocimeters (LSV). Founded in 1967 and headquartered in Waldbronn, Germany, Polytec develops precision non-contact measurement instruments used in vibration analysis, structural dynamics, and surface velocity measurement across research and industrial applications.

Polytec's laser vibrometers use the Doppler effect to measure surface velocity and displacement with nanometer-level resolution without physical contact with the test object. This non-contact approach is essential when measuring delicate structures, rotating components, or objects in environments where conventional contact sensors cannot be applied.

Key Product Lines

• Scanning laser Doppler vibrometers (SLDV) for full-field vibration mode shape analysis
• Single-point laser vibrometers for precision vibration measurement in R&D and production
• Laser surface velocimeters (LSV) for non-contact speed and length measurement in manufacturing
• Fiber-optic and miniature vibrometer sensors for harsh or confined environments

Industries Served

Polytec equipment is used extensively in automotive NVH (noise, vibration, harshness) testing, aerospace structural dynamics, MEMS and semiconductor characterization, acoustics research, ultrasonic testing, biomedical research, and consumer electronics quality control. Their instruments are found in university laboratories, national metrology institutes, and aerospace & defense research centers worldwide.
