    Ocean Optics ISS-UV-VIS Integrated Sampling System for Relative Absorbance

    The ISS-UV-VIS Integrated Sampling System is a combination RF deuterium source with a tungsten bulb in a housing connected to a holder for 1-cm cuvettes. This sampling system couples to an Ocean Optics spectrometer with optical fiber to create a small-footprint system for relative absorbance.

    About the D-alpha Line:

    All deuterium-tungsten halogen sources have a D-alpha line, revealed as a jagged peak in the visible portion of the spectrum, that produces "unbalanced" output in the deuterium and tungsten halogen sources. Correcting for this deuterium line -- a sharp spectral feature near 655 nm -- is difficult. For example, if you adjust spectrometer integration time to reduce the intensity of this saturated spectral line, the efficiency of the system at UV wavelengths drops significantly, compromising signal-to-noise performance. Also, spectrometer efficiency is greatest in the same general spectral range as the 655 nm line, exaggerating its effects.

    Proprietary Filtering Technology :

    Using the same high-precision patterned dichroic filter technology that distinguishes Ocean Optics Linear Variable Filters, the DH-2000-BAL balances the intensity of the deuterium and tungsten halogen sources, producing a "smoother" spectrum across the entire wavelength range and eliminating problems associated with saturation. By comparison, most combination UV-NIR sources can be adjusted for relative intensity only

    Optical Fibers:

    We recommend using Ocena Optics solarization-resistant optical fibers with all versions of the DH-2000-BAL.

     

    Features:

    • Manual or software-based operation
    • Ability to hold a 1-cm square cuvette
    • Spring-loaded ball plunger screws for precise cuvette positioning
    • 7-1/2" x 4" size and <1 lb. weight
    • 5-mm diameter f/2 collimating lens
    • 12 VDC power supply and power cord

    Note: This sampling system is best used with Ocean Optics' 300 µm solarization-resistant optical fiber.
