Datasets containing the wavelengths at a 1 nm interval and fractional total transmittance for a clear polyester film and a yellow theatrical "gel".

Usage

two_filters.spct

two_filters.mspct

polyester.spct

yellow_gel.spct

Format

A filter_spct object with 611 rows and 2 variables. Individually as filter_spct objects, and together as a collection stored in a filter_mspct object and in a long-form filter_spct object.

An object of class filter_mspct (inherits from generic_mspct, list) with 2 rows and 1 columns.

An object of class filter_spct (inherits from generic_spct, tbl_df, tbl, data.frame) with 454 rows and 2 columns.

An object of class filter_spct (inherits from generic_spct, tbl_df, tbl, data.frame) with 425 rows and 2 columns.

Details

  • w.length (nm).

  • Tfr (0..1).

  • spct.idx (names, only in two_filters.spct).

Note

Package 'photobiologyFilters' contains data sets for hundreds of optical filters and materials in objects of these same classes, ready to be used with package 'photobiology'.
