CAVILUX® Smart UHS for Ultra High-Speed Illumination

CAVILUX Smart UHS is a powerful pulsed diode laser light source with very short pulses and very high repetition rates. It is an ideal light source for ultra high-speed cameras up to 10 MHz.

CAVILUX Smart UHS can generate pulsed light power of hundreds of watts at as short as 10 ns pulses. The light output is essentially monochromatic with low degree of coherence, which is ideal for illumination purposes as there are no chromatic aberrations or speckle.

Benefits

  • High power and very short pulses down to 10 ns
  • Ideal light source for schlieren and shadowgraphy applications
  • Excellent for ultra-high-speed imaging with short pulses
  • Versatility by varying pulse duration and repetition rate
  • Monochromatic and low-coherence light
