Cavilux high speed laser illumination systems

Cavilux systems are based on specially developed diode lasers with which challenging industrial processes can be made visible in conjunction with industrial cameras or high-speed cameras

Supplier: Cavitar

Technology type: High-speed Laser Illumination

For image or film recording of very fast and macroscopic processes, additional lighting is usually required. Cavitar Ltd. has developed powerful diode lasers for this purpose, which are free of coherence and are able to suppress even strong process light, such as that produced by MAG, MIG, TIG or TIG welding processes, thus enabling very high-contrast film recordings.

The very short and freely selectable laser pulse durations down to 10ns can massively reduce motion blur in very fast processes, such as ignition processes or shock waves and produce very clear images. The short flashes of this laser illumination have the advantage over illumination by a continuous wave laser (CW laser) that the actual process to be observed is not affected by unnecessary heat input from the illumination itself. A basic distinction is made between two versions of the Cavilux systems, the Cavilux HF and the Cavilux SMART system. The HF system delivers more laser power and is therefore used with strong broadband (white) process light, as is the case with all plasma processes. The SMART system on the other hand, delivers very short pulse durations of up to 10 ns, which is very helpful in the area of ultra-fast processes such as shock waves in schlieren images to greatly reduce motion blur.

Powerful pulsed high frequency laser light source
Visualisation of demanding applications
Ideal for high temperature applications
Precise recording of processes even of small and fast moving objects
Short pulses eliminate motion blur and therefore more accurate images for process analysis
Various options for lighting optics, even for applications where space is very limited

For the visualisation of welding processes such as MAG, MIG, WIG or TIG
For picking up very fast and small objects such as cavity bubbles, projectiles or ignition processes
For the optimisation of 3D welding processes, the so-called additive welding or additive manufacturing
Optional configuration for schlieren recording in transmitted light (backlighting)
Visualisation of shock waves in media such as air or transparent liquids
