filters.mspct {photobiologyFilters}

Spectral transmittance of diverse optical filters

Description

A collection of transmittance spectra for optical filters and similar materials from different suppliers. We include under "filters" all semi-transparent and transparent sheets and films with homogeneous optical properties. We exclude "screens" such as nets, cloths and perforated films with heterogeneous optical properties.

Usage

filters.mspct

Format

A "filter_mspct" object containing several "filter_spct".

Details

The "filter_mspct" object named filters.mspct contains a collection of "filter_spct" objects with spectral transmittance data for filters.

The variables in each member spectrum are as follows:

• w.length (nm)

• Tfr (transmittance expressed as a fraction of one)

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

Note

Please see the help for the indexing vectors for specific details.
