metals.mspct: Total reflectance of metals at 294 K

In photobiologyFilters: Spectral Transmittance and Spectral Reflectance Data

Description

Total reflectance of metals at 294 K, measured using an integrating sphere. Data are to be used as "reference values only" as actual values will depend on the state of the metal surface and its polish.

Usage

metals.mspct

Format

A reflector_mspct object containing a collection of reflector_spct each with 47 rows and 2 variables.

Details

The variables for each spectrum are as follows:

• w.length (nm)

• Rfr (fraction)

Note

Data extracted from a published report by OCR.
