Illumination System
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
"It's the little details that are vital. Little things make big things happen."
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
