Vibrometer with fixed focal length • High-precision, non-contact vibration and length measurement • easy adjustment and handling • compact device with case for mobile use • the measuring system with a fixed focal length • fixed working distance customized 30 ... 70 mm, 240 mm, 480 mm, • laser spot diameter 12 ... 30 µm, 100 µm, 200 µm • FFT software for spectral analysis • extensive trigger options • open interfaces for OEM software under Windows and Linux Many applications in industry and research require highly precise and informative vibration analysis on a wide variety of surfaces. Non-contact vibration and length measurement on surfaces of any roughness and under industrial operating conditions can be realized very precisely and quickly with the LSV 120 NG vibrometer. The laser vibrometers from this series have integrated optics with a fixed working distance. The focusing lens is installed in the sensor head and is thus protected against damage and environmental influences. Therefore, this basic variant is preferred for OEM applications in industry. The surface of the moving object may have any roughness. Mechanical vibrations with amplitudes up to ± 20 mm can be measured in the range from 0 to 5 MHz with a resolution in the sub-nanometer range. Static measurements are also possible with this measurement system. The design of the vibrometer is as compact as it is robust. Its housing is splash-proof and the optical fibers are supplied with protective jackets on request.
