    Our Spectrally Tunable Light Sources

    Our tunable light sources allow you to scan a wide range of wavelengths in a short time with monochromatic single wavelengths. We cover the entire spectral range from DUV to MIR.
    To do this, we use light sources with high power and luminance and combine them with monochromators that we have developed specifically for this purpose. We look forward to your inquiry: +49 (0) 551/270765-0, info@lightsource.tech

    Discover our tunable light sources:

    Monochromator-F Fiber-to-Fiber-Monochromator

    • Wavelength range 190 nm – 5,5 µm
    • Plug and play optical gratings
    • Use any fiber coupled light source

    Monochromator-H with integrated halogen lamp

    • Wavelength range from 340 nm to 2,0 µm
    • Cost effective solution for medium power applications
    • Ideal for spectroscopy and sensor testing

    Hyperchromator for the XWS-30 from ISTEQ

    • All wavelengths from DUV to NIR
    • Developed for the laser-pumped XWS-30 light source from ISTEQ
    • Plasma as entrance slit

      A shining example: Application that uses our tunable light sources

      Application Note: Hyperspectral Microscopy

      Application Note: Hyperspectral Microscopy

      In this application note we demonstrate a hyperspectral microscope by combining some of our products.

      The product range from lightsource.tech offers fiber-coupled light sources and optical accessories that harmonize perfectly with our tunable light sources. The LS-BB1 is one light source for the Monochromator-F that covers the spectrum from VIS to NIR and can be a powerful alternative to conventional halogen light sources. Even more powerful is the fiber-coupler that transforms the free beam of the XWS-30 from ISTEQ into a point light source with a wavelength range from DUV to NIR. Both the Monochromator-F and the Hyperchromator, the latter of which is already integrated into the XWS-30 as the standard light source, can be combined with the homogenizer. The monochromatic light of the homogenizer illuminates a square field very homogenously.
      If you would like to find out more about our modular system or which tunable light source in our product range suits your set-up best, we would be pleased to advise you personally and, should you wish, make an individual offer for a complete system from lightsource.tech.
