• CAVILUX™ HF for High-Speed Illumination

    CAVILUX HF is a versatile and powerful high-performance pulsed diode laser light source. It is very suitable light source for high-speed cameras, and an excellent and versatile tool for scientific and industrial R&D work.

    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
