CAVILUX Smart

CAVILUX Smart can generate pulsed light power of hundreds of watts., 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. CAVILUX Smart can generate arbitrary pulses or bursts of pulses with precisely adjustable duration for the length of each individual pulse and each delay between pulses.


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

Overview

  • Powerful and versatile pulsed diode laser light source designed for high-speed imaging and monitoring

  • 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

  • Possibility to generate up to five pulses per one camera exposure

  • 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

  •  Light is immune to surrounding lighting conditions such as ambient or sunlight, as well as to process vibrations
