For best signal and data quality on poorly reflective surfaces or on objects far away, Optomet developed the SWIR (Short Wavelength Infrared) laser vibrometer. The invisible measurement beam is positioned using a coaxial green targeting laser.
With a wavelength of 1,550 nm and up to 10 mW of laser power, ten times the output power is available compared to a HeNe laser – while having the highest eye safety class (Class 1). In conjunction with the three-fold higher efficiency of the photodetectors, infrared vibrometry creates the conditions for sufficient signal quality for almost all vibration measurement tasks – regardless of the measurement distance, thanks to a single longitudinal laser mode. High temperature stability and a long service life offer additional added value.
Even on dark, rough or surfaces with low reflectivity, there is no need to treat the measurement surface when using the Optomet SWIR Laser vibrometer. Measurements over long distances, on glowing surfaces or even on biological tissue are the types of challenging applications where the Optomet SWIR vibration measurement technology truly shines.
