XWS-X

BROADBAND PLASMA LIGHT SOURCE

ISTEQ’s XWS-X light source product has been designed for those customers who need a powerful light source with high UV generation.

  • Significantly higher brightness across the whole spectral range in comparison to XWS-65 UV
  • Maximum spectral brightness up to 140 mW / (mm² sr.nm)
  • x6 Brightness improvement at UV range below 250 nm in comparison to XWS-65 UV
  • Extreme temporal and spacial stability: STD 0.05%



XWS-X - laser pumped plasma ultrabright broadband light source

In XWS sources, plasma emits light due to the interaction between a continuous energy input from a laser and the gas medium used (optical discharge).
These light sources have been developed as a replacement for traditional gas discharge lamps (Xenon, Deuterium, Tungsten, etc.) and LEDs.
Compared to these, XWS sources have a wider spectral range and higher spectral brightness.

Available with retroreflector
Available in Dual Port configuration
Output configuration: Free space or FCU
Available with Air Cooled/Water Cooled Optical Head
External source control and parameters monitoring by Laptop/PC via:
RJ45 (Ethernet, Web interface),
COM-port (RS-232)
