In XWS sources light is produced by plasma which emits light due to the continuous energy input from a laser (optical dis- charge). These light sources have been developed as a replacement of tradi- tional gas discharge lamps (Deuterium-, Tungsten-, Xenon- lamps etc.) and LEDs. Compared to these, XWS sources have a wider spectral range and higher spectral brightness. Moreover, the technology of plasma light sources allows developing units with specific characteristics which match special customer applications. Main advantages: ▪ broad spectral range; XWS-65 light source is available in 2 configura- tions. The Ozone-free configuration offers a spectral range from 240nm to 2700nm. The UV configuration offers a spectral range from 180nm to 2700nm. A broad spectral range allows sub- stituting several conventional light sources ▪ high spectral brightness; ▪ high temporal and spatial stability; ▪ the small dimensions of the emitting volume considerably expand the range of XWS applications; ▪ long operation, due to no wear of lamps and electrodes. Principle of operation: Operation of XWS sources is based on a phenomenon of optical discharge in high pressure xenon. Initial plasma is produced by a high voltage electrical discharge in xenon. Plasma state of xenon is sustained by a focused continuous laser radiation. Compared to arc lamps, laser plasma has higher spatial and temporal stability, higher brightness, smaller dimensions of emitting volume and considerably longer operation without lamp replacement.
