CAVILUX HF UHS

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.


Benefits

  • 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

Overview

  • Excellent for ultra-high-speed imaging

  • Accurate imaging of processes involving extremely small and/or fast objects – without motion blur

  • Visualization of hot and bright objects – without blinding brightness

  • Versatility by varying pulse duration and repetition rate

  • Changeable illumination optics provides flexibility

  • Efficient lighting of processes even in limited space and hard-to-reach places

  • Monochromatic and low-coherence light ensures the best possible image quality – without chromatic aberrations or speckle
