The XWS-T150 and XWS-T266 tunable light sources are built upon cutting-edge ultra-bright laser-pumped plasma sources XWS-65 from Isteq B.V. and the proven wide-aperture monochromators M150 and M266. These systems deliver exceptional spectral power density across a broad range—from 190 nm to 2500 nm—making them ideal for demanding metrological applications.
Key highlights:
- Broad Spectral Coverage: From deep UV (190 nm) through NIR (up to 2500 nm).
- High Power Density & Stability: The XWS-65 light source outperforms traditional discharge lamps with significantly higher spectral brightness, superior spatial and temporal stability, and longer operational lifetime.
- Optimized Performance via Monochromator Selection:
- M150: Compact, efficient, and ideal for general applications
- M266: High-resolution, fully automated monochromator with double the focal length of M150. This allows:
- Twice the spectral resolution
- Or 2× wider slits, yielding up to 4× higher optical output power.
- Imaging Optics: Both monochromators include astigmatism-compensating optics for enhanced spectral fidelity.
- Example Configuration: XWS-M150 with 1200 grooves/mm (blazed at 250 nm) and 300 grooves/mm (blazed at 500 nm) gratings enables high spectral power in the 200–1100 nm range.
Thanks to their versatility, stability, and unmatched performance, the XWS systems are indispensable for precision spectroscopy, calibration tasks, and other applications requiring tunable monochromatic light.
