CAVILUX Smart illumination laser provides extremely short pulses with very high power. The shortest pulse that is possible with the full power is 30 s. However with reduced power a pulse length of 10 ns is possible. Such short pulse lengths are ideal to study high speed phenomena such as shock waves, ballistics and also for visualizing small particles under a microscope e.g. ink jet droplets or sprays.

CAVILUX Smart can be also used for thermal light emitting processes like welding and explosions when the desired frame rates are about 1000 fps. CAVILUX Smart is very compact and robust and can be used in the lab as well as in rough industrial conditions. The fiber guides enable the use of the light in tight spaces.

Target applications include:

  • Shock-waves
  • Flows of particles, droplets, sprays
  • Welding and coating
  • Ballistics
  • Explosions

Wavelength

If visible light is necessary, then CAVILUX Smart 640 nm is the standard product (not taking into account possible customized solutions). The CAVILUX HF is equipped with a visible laser pointer beam (green light). Color cameras typically have an IR cut filter in front of the sensor which blocks 810 nm. Some cameras allow the removal of that filter and in this case CAVILUX 640 nm and 810 nm can be used.

Fiber core diameter

CAVILUX Smart has a fiber core diameter of either 5 mm (400 W @ 640 nm) or 3 mm (500 W @ 810 nm, 200 W @ 640 nm), whereas CAVILUX HF has a fiber core diameter of 1.5 mm. This means that CAVILUX HF has 4-11 times higher brightness than CAVILUX Smart. Higher brightness enables the illumination of a smaller area from a certain distance or, alternatively, the illumination of a certain area from a greater distance. CAVILUX Smart 200 W provides a higher brightness than CAVILUX Smart 400 W if the illuminated area is smaller than 3 mm.

Minimum pulse duration

The minimum pulse duration for CAVILUX Smart enabling full output power is ~30 ns. CAVILUX Smart can create pulse durations up to 10 ns but then the output power is lower. The minimum pulse duration for CAVILUX HF at full power is ~100 ns and 50 ns at lower output power. A very short pulse may be needed for removing motion blur when a small and fast-moving object is studied at high magnification. CAVILUX Smart has shorter rise and fall times than CAVILUX HF. Therefore, Smart can generate extremely short pulses (below 100 ns) more accurately than CAVILUX HF.
