Julight VSM series (VSM = Vibrometer Self-Mixing) Laser Vibrometers are compact and versatile instruments based on the innovative Self-Mixing Interferometry principle (SMI), for non-contact vibration measurements with high sensitivity and flexible working distance.
The measurable vibrations range from few tens of pm, to tens of mm, for frequencies from DC up to 100kHz, or 10MHz (with the ultrasound extended bandwidth option).
Julight Laser Vibrometer are capable of measuring directly onto any type of diffusive surface, without the need to use retroreflective painting or stickers, up to several meters distance. Working distance goes from 100mm to 5m for standard versions based on laser safety class 1 infra-red measuring laser, and up to 30m with long-distance option and laser safety class 3B.
TO SATISFY ANY VIBRATION MEASUREMENT NEED
heads integrated into one
single instrument
with 3 optical heads
(also scanning)
measurements of extended objects
onto different test points
operation (the IP68 optical head
can be submerged)
measurement of small-sized
and delicate objects
The flexible and modular Julight approach allows to combine Laser Vibrometer heads and Laser triangulation heads within the same instrument, for unprecedented versatility and to satisfy any measurement need.
VSM series Laser Vibrometers can be controlled by a PC using a dedicated software that communicates via Ethernet.
