    Our spectrally tunable light sources

    For the efficient generation of monochromatic light: the Monochromator-F and Hyperchromator

    Efficient spectral isolation can only be performed with a monochromator that allows, firstly, fast and precise tuning over a broad spectrum, and secondly, the least possible loss of light.

    We look forward to your enquiry.

    Tunable light sources from lightsource.tech meet these requirements: The Monochromator-F is equipped with pre-adjusted, easy-to-change gratings and covers the wavelength range from UV to MIR. The Hyperchromator was developed especially for the XWS-30 light source from ISTEQ and its very broad spectrum from DUV to NIR. Light loss is reduced significantly by using the plasma itself as an “entrance slit”.

    Both the Monochromator-F and the Hyperchromator can be integrated reliably and without risk of failure via multimode fibers into existing set-ups and into all commonly used software environments.

      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.
