Digital Laser Doppler Vibrometer Nova-Series SWIR Single-Point Laser Vibrometer Vibrometry in the short-wave infrared range for maximum signal-to-noise ratio. Delivers best signal quality for dark or rough surfaces, biological tissue, as well as long working distances. IDEAL FOR • Dark / rough surfaces • Very high-frequency vibrations • Biological surfaces • Moving or rotating objects • High speed vibrations up to 25 m/s • Long distance measurements HIGH-END AND BEST-PERFORMANCE The Nova Series Laser Vibrometer operates with an invisible SWIR laser (1550 nm). At a wavelength of 1,550 nm, ten times the laser power of a HeNe system is available for measurements without compromising the eye safety. The Nova Series comes in when maximum dynamic range is required or every decibel of signal level counts. Typical use cases are surfaces that poorly reflect visible light, for example dark and rough surfaces or biological tissue. A high signal strength is also of vital importance for measurements over long distances, e.g. in civil engineering or
