The NOVA Series comes in when maximum dynamic range is required or every decibel of signal level counts. Typical use cases are surfaces that poorly reflect visible light, for example dark and rough surfaces or biological tissue. Signal strength is also of vital importance for measurements over long distances, e.g. in civil engineering or aerospace.
The key to this lies in the infrared range of the SWIR laser source. At a wavelength of 1,550 nm, ten times the laser power of a HeNe system is available for measurements without compromising the eye safety. At the same time, measurements up to 10 MHz with vibration velocities of up to 24.5 m/s are possible. In connection with different optical systems and decoders, the NOVA is up to virtually any vibration measurement task. A coaxially guided laser in the visible range facilitates the positioning of the measuring point.
A detailed list of all vibrometer characteristics, including all hardware and software features, can be found in the vibrometer data sheet in Support & Datasheets.

A wide variety of high-performance real-time decoders are available for the evaluation of the interferometric measuring signals. The OptoMET UltraDSP technology enables the measurement of frequencies up to 10 MHz and vibrational velocities up to 24.5 m/s with the Nova-Series, displacements can be resolved to less than 100 fm. All vibrometers incorporate a velocity decoder, and displacement and acceleration decoders are optionally available. Numerous measuring ranges per decoder ensure that measurements can always be performed with the optimum sensitivity.
Decoders can be easily retrofitted or upgraded. Start with a basic system and adapt the capabilities of the measuring instrument as required. This requires no return of the instrument to the factory and no waiting times for your production or research project. The table below provides an overview of the configuration options. We will also be happy to assist you in the selection of the best decoder for your measuring task.

Several lenses are available which are optimized for the Nova-Series. Choose the right optical system based on working distance, reflectivity of the surface to be measured or size of the focus point. The lenses are easily exchangeable due to a bayonet lock as on single-lens reflex cameras.
