Vibrometer with variable focal length

LSV 2500 NG

Laser vibrometer with variable focal length (zoom lens)

high-precision, non-contact vibration and length measurement

frequency range from 0 Hz to 5 MHz

easy adjustment and handling

compact device with case for mobile use

extensive trigger options

infinitely adjustable working distance in the range 240 mm to 2500 mm

FFT software for spectral analysis

open interfaces for OEM software under Windows and Linux

The LSV 2500 NG series of vibrometers with manual zoom lens offers maximum ease of use and flexibility and is based on the LVS 120 NG sensor.
Optical working distances between 240 and 2,500 mm are covered with the zoom. The features of the LSV 2500 NG vibration meter always prove advantageous when variable measurement tasks need to be solved and the vibrating measurement object cannot be placed directly in front of the vibrometer.

Measurements through optical windows when objects are located in vacuum chambers, for example, are also possible.
All other system features correspond to the LSV 120 NG model.
