SPEKTRA designs, develops, produces and provides calibration services for vibro-acoustic metrology systems - with highly efficient electrodynamic drive systems for high frequency exciters

SPEKTRA (SPEKTRA Schwingungstechnik und Akustik GmbH), founded in 1994 and headquartered in Dresden, Germany, is a high-tech company that designs, develops and produces vibro-acoustic metrology and calibration systems and provides calibration services. The products are developed and manufactured for the purpose of metrological calibration and extend into the fields of structural testing and quality control. Our products include vibration, shock, acoustic, dynamic pressure and dynamic force calibration and test systems. We are unique in the world as a leading manufacturer of vibration and acoustic measurement instruments with the highest standard of absolute vibration calibration laboratories and calibration services available.

SPEKTRA has over 20 years of experience in the calibration of transducers, supplying equipment to international institutions and industrial laboratories at all levels, and its highly skilled team can provide customised products and engineering solutions. SPEKTRA is certified to ISO 9001 (TÜV) and is an ISO 17025 accredited calibration laboratory (DAkkS).

High frequency shakers
Innovative high frequency shakers with an efficient electrodynamic drive system. the SE-29 offers a very wide frequency range and low transverse vibration. Due to its wide temperature range and high payload, the SE-29 is ideally suited for large sensors or geophones. In addition to the high quality of the components, the focus is on versatile application areas and easy implementation in existing test environments.
