uqg_filters: Total transmittance for UQG filters
In photobiologyFilters: Spectral Transmittance and Spectral Reflectance Data

Description Usage Format Details DISCLAIMER Note Examples

Total transmittance for UQG optical glass absorptive and interference (dichroic) filters. Data measured by P. J. Aphalo with an Agilet 8453 array spectrophotometer. Some of the filters are Schott glass and we have retained the Schott type names.

A vector of character strings.

The variables are as follows:

w.length (nm)
Tfr (fraction)

These spectral transmittance data are based on the measurement of a single filter of each type. Filters from other production batches may differ in their spectral properties, specially for wavelengths outside the range described in the manufacturer's published specifications. The characterisitics of some types of glass filters may change with time through surface oxidation or by effect of exposure to radiation including solar radiation. The data provided is to be used only as a coarse guide. When filter properties are important the filter actually used should be measured.
