CAVILUX® HF UHS for Ultra-High-Speed Imaging

CAVILUX HF 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 5 MHz.

CAVILUX HF UHS can generate pulsed light power of hundreds of watts at as short as 50 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.



  • High power and brightness (up to 500 W coupled to a 1.5 mm diameter fiber)
  • Ability to generate pulses up to 5 million fps
  • Minimum pulse length of 50 ns
  • Monochromatic and low-coherence light
  • High flexibility through fiber optics and changeable illumination optics
