    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.

No restocking fee will be assessed, however, the customer is responsible for the return shipping costs. Full credit will be issued upon receipt and inspection of the item(s) to ensure equipment was returned in the same condition it was initially shipped out in.

    Important Information

    All exchanges and returns require the completion of a Return Merchandise Authorization (RMA) form. Once completed, please return the merchandise immediately as the RMA number is only active for ten (10) days from the date of issuance.
