Nist reflectivity software

Each calibration results in a calibration report is issued, which includes the calibration values and uncertainties for the customer-supplied test item s. These standards have shown insignificant spectral variation from batch to batch and from one manufacturer to another.

Transmittance and absorbance data from this paper can be download as an Excel file kB. NIST continually strives to improve its capabilities for providing these measurements and add to the general knowledge by performing research on related topics. Share Facebook.

Summary NIST maintains the national scales for reflectance and transmittance in the ultraviolet, visible, and near-infrared spectral regions nm to nm. The platforms supported for the downloadable programs are indicated within the web pages.

They are currently being maintained at ANL, with links provided here for your convenience. Support for the reflectivity programs: paul. In addition to the resources above, there are a number web-accessible tools for experimental planning and simulation:.

There are a number of software packages listed above that are relatively mature and some that are in the development phase. The two major efforts currently in the development phase are the DAVE project and reflectivity software development.

The user-generated SLD profiles can be exported to a heavily-commented Python Refl1D model file to provide an easy way to get started with modeling data in Refl1D. Please see the article in J. NIST for more details.

For example: The Refl1D program was used for elements of the data analysis[1]. Web Reflectivity Calculators For quick data exploration we provide a browser-based magnetic reflectivity calculator as well a non-magnetic unpolarized reflectivity calculator.
