Laser Doppler Vibrometer OFV-5000

The laser vibrometer OFV-5000 with a compact fiber-coupled sensor head OFV-534 from Polytec combines precise optical-based vibration measurements with the easy and rapid operation. It works completely without contact and measure vibrations of even small and lightweight components with very high accuracy.
Laser Engraver

The laser engraving machine is an electro-mechanical device capable of engraving and cutting different materials (such as wood, MDF, acrylic, cardboard, and leather etc.) with high precision via computer programming.
Spectrum DN2.813-04

The hybridNETBOX DN2.80/81x system consists of a Digitizer and an AWG that can work in sync or independently. It allows simultaneous signal generation and data acquisition for stimulus-response tests, ATE applications, MIMO applications, or closed-loop applications. Used independently, the digitizer can acquire test data in the field and the AWG can replay this test data in the lab.
Olympus transducers

The Olympus contact transducers are single-element special transducers intended to excite the test specimen within a particular frequency range. They can be used to test a wide variety of materials for transmission tests, perform material characterization, and inspect a wide variety of metallic and non-metallic components.

LIMESS Q400 Digital Image Correlation system

With the Q400 system, the 2D or 3D deformation analysis is performed in a precise, fast, and user-friendly manner. The modular system is also characterized by the high flexibility of the optical setup and thus can be optimally adapted to the application. The intuitive measurement software Istra4D also provides the associated measurement accuracy for each measured value (displacement, deformation, strain, 3D coordinates, etc.). Thanks to optimized algorithms, Istra4D can resolve local effects, e.g. in crack growth, better than other DIC systems. Using a special cluster approach, up to 16 cameras can be used in a Q400 system, which achieves better surface coverage for complex component geometries and higher measurement accuracy.
WMA-320 High voltage amplifier

The Falco Systems WMA-320 is a high voltage, high-speed laboratory amplifier for demanding applications. Its wide bandwidth and large voltage range make it an excellent choice for use with MEMS devices, EO-modulators, piezo positioning systems, beam steering components, ultrasonics, and many more.
