The Polytec OFV-5000 Modular Vibrometer is a 0.2-2m non-contact laser doppler vibrometer with a frequency range of DC - 24 MHz that includes a customizable laser turn head and customizable compact sensor head. The Polytec OFV-5000 allows you to choose from different sensor heads to best suit your specific measuring task and configure the decoders regarding the required vibrational displacement, velocities and acceleration. Both analog and digital decoders are available, giving a frequency range from near DC to 24 MHz with velocities up to ±10 m/s and displacements from the picometer to meter range.
