metals.mspct: Spectral reflectance of metals

In aphalo/photobiologyFilters: Spectral Transmittance and Spectral Reflectance Data

Spectral reflectance of metals

Description

Total reflectance of metals at 294 K (21 C), 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 named metals.mspct containing a collection of reflector_spct objects each with 47 rows and 2 variables.

The variables for each spectrum are as follows:

• w.length (nm)

• Rfr (fraction)

These member objects contain metadata stored as R attributes. Accessors to the metadata are available: what_measured(), how_measured(), when_measured(), and comment().

Note

Data extracted from a published report by OCR.
