    When you invest over $10,000 on a UV VIS spectrophotometer why not make sure it is calibrated correctly?

    Features: Specifications:
    SOLID-STATE STANDARDS! NEVER REPLACE! NEVER RECALIBRATE! Easy to use and handle. Can be used in ANY spectrophotometer. Guaranteed. These Reference Standards correspond or exceed requirements of NIST930e established by NIST National Institute of Standards & Technology, USA.
    1. Highly accurate and consistent spectrophotometer calibration every time
    2. Never have to be replaced, one kit will last forever

    This UV/VIS calibration kit can test the following:

    • Photometric Accuracy - In the UV and VIS range
    • Stray Light Performance of Spectrophotometers- in the UV and VIS range

    This kit meets or exceeds all the requirements of NIST930e standard.
    NIST Traceable data tables/charts are available for qualified customers.

    Liquid and Solid-State Neutral Density filters for testing photometric accuracy of spectrophotometers are typically calibrated by the filters' manufacturers, and the corresponding filters performance certificates are supplied to customers.  Whereas solid-state filters typically maintain their performance for many years, performance of liquid filters degrades much quicker due to so-called slow irreversible chemical reactions, photonic-promoted chemical reactions, and certain other reasons.Therefore, manufacturers of liquid filters typically request customers to replace liquid filters every 1 to 3 years.

    At the same time, until recently solid-state neutral density filters had substantial non-linearity across their surface which caused substantial contribution to so-called "Expanded Uncertainty"*. This was a disadvantage of solid-state neutral density filters.
     *As defined by NIST. 

    Modern development of nano-technology allowed us to develop state-of art solid-state quantum resonance filters towards replacing liquid filters, such that customers can benefit from substantial savings on filters' replacements.

    Our proprietary nano-deposition and nano-embedded technology overcomes the said disadvantage of using solid-state neutral density filters comparably to liquid-based filters while preserving all the advantages of solid-state neutral density filters. Moreover, our composite medium allows using our solid-state neutral density filters for calibration and research and development purposes of our customers not only for the NIST wavelengths but also at ANY wavelength within the optical wavelength ranges of operations of our solid-state neutral density filters.

    The optical wavelength range of operations of our FUV-1 Stray Light/Photometric Accuracy Filter is 200-700 nm and 400-700 nm for the other neutral density filters included in this kit.

    Photometric data tables are available for qualified customers. Please contact us for more information.

    The instruction on how to use this kit is included with the every sold product.

    This kit includes:
    1 Neutral Density Filter H-F2-0.25
    1 Neutral Density Filter H-F3-0.5
    1 Neutral Density Filter H-F4-1
    1 Stray Light Filter FUV-1
    1 Case CaseP4
