    Broadband LED Light Sources

    Unique spectrum: The LS-BB1

    With our LS-BB1 we have developed a fiber-coupled broadband LED light source. Its wavelength range of 420 bis 900 nm allows a wide variety of spectroscopic applications. By covering a broad spectrum from VIS to NIR, this is a powerful alternative to halogen light sources. The high luminance of the single LED chip and efficient coupling into multimode fibers of up to 1 mm give rise to flexibility and a bright point light source.
    The LS-BB1 is light and compact, making it simple to integrate into experiment set-ups. Its lifetime of over 10,000 hours is due to the well-thought-out thermic design of the broadband LED light source.

      Broadband LED light source LS-BB1
      Large wavelength range from VIS to NIR from a single LED

      Compared to other LED light sources available on the market, the LS-BB1 covers a very large wavelength range of 420 – 900 nm. With just a single LED chip it delivers light not only in the complete VHS spectrum but goes beyond this to offer convincing performance in NIR to 900 nm.
      With this large wavelength range and a light output of up to 20 mW, the LS-BB1 fiber-coupled broadband light source is a powerful substitute for halogen light sources and can be used for many spectroscopic applications.

      We look forward to your enquiry.

        Our HighLight: The converter phosphor, suitable for spectroscopy

        White light LEDs for general lighting purposes only have a narrow spectrum adapted to human perception and are therefore not well-suited to spectroscopy. The LED of the LS-BB1 generates a large spectral bandwidth and high luminance thanks to the specially developed phosphor converter.

        This makes it especially suitable for spectroscopic applications in the VIS-NIR range.
