Illumination System

Cavitar Logo.png


Typical application examples include welding, flow and spray studies, material testing, ballistics and explosions. CAVILUX HF is compatible with schlieren and shadowgraphy optical solutions.

The high maximum duty cycle (2 %) of CAVILUX HF enables it to operate at frame rates up to several hundreds of thousands of frames per second.


High power and brightness (up to 500 W coupled to a 1.5 mm diameter fiber)

Ability to generate pulses at high speed (e.g. 20.000 fps) or ultra-high-speed (e.g. 1 million fps)

Pulse length from 50 ns to 200 µs possible

Monochromatic and low-coherence light

High flexibility through fiber optics and changeable illumination optics

  • Powerful high-frequency pulsed diode laser light source for visualization of demanding applications

  • For high-temperature processes – see through heat and blinding brightness

  • Accurate imaging of processes involving even extremely

  • small and/or fast objects

  • Ability to generate pulses at high speed

  • Versatility by varying pulse duration and repetition rate

  • Shortness of pulses eliminates motion blur – better and more accurate images for analyzing

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

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

  • High flexibility through changeable illumination optics that enable setups even in limited space and with long working distances



  • Consists of a control unit, laser unit(s), control software and illumination optics

  • One control unit can drive 1…4 laser units (including CAVILUX Smart) and

  • synchronize 1…4 cameras

  • Can receive or provide 5 V TTL signal for camera synchronization

Laser unit(s)

  • Wavelength options 640 nm (visible) and 810 nm (invisible)

  • Output power options for

  • Green laser pointer for easier alignment

Variability through generation of pulses and pulse patterns

  • Pulse duration 50 ns … 10 μs (also 200 μs for 810 nm on request)

  • Duty cycle 2 % for max 10 s (also ultra-high-speed mode available)

  • Continuous mode with 0,3 ‰ duty cycle

  • Generation of single pulses or bursts of pulses (max 5 pulses / bursts) at high

  • repetition rate

  • Practical repetition rates up to a few hundred kilohertz

  • Stand-alone operation

Versatility through changeable fiber optic illumination

  • Adjustable illumination with lens (standard solution)
