Traditional laser Doppler vibrometers (LDV) with helium-neon (HeNe) laser sources have been a useful tool for non-contact vibration measurement for many years. Optomet has perfected HeNe based laser vibrometry with the Vector series. The Vector series with a laser wavelength of 633 nm enables the non-contact vibration measurements of objects of microscopic to macroscopic sizes with the highest accuracy and precision.
The Vector series is the standard vibrometer for a wide range of vibration measurement problems. It is particularly suitable for surfaces with high to moderate surface reflectivity, for measurements on or below the surface of water and for applications in which the smallest laser spot size is critical.
Helium-Neon lasers have a wavelength of 633 nm and are able to shine through water with minimal loss of laser power. HeNe vibrometers are therefore indispensable if there is a layer of water between the vibrometer and the vibrating measurement object.
Due to their short wavelength, HeNe lasers allow the measurement beam to be optimally focused on the order of micrometers. They are therefore the ideal choice for measurements of the smallest features or microstructures.
Further properties common to all Optomet vibrometry systems such as universal digital signal processing, real portability or intuitive hardware and software are described in more detail in the product-overview.
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 25 MHz and vibrational velocities up to 10 m/s with the Vector 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.
