photobiologyFilters 0.5.2

Package documentation web site at:

The main changes from version 0.5.1, the current CRAN version, released 10 months ago are:


  • Add data for some Chinese absorptive filters from Yixing Purshee Optical Elements Co., Ltd.
  • Add thickness metadata for several photography filters.
  • Add reflectance data for various materials (previously contained in package ‘photobiologyReflectors’.
  • Add refraction index data.
  • Update the User Guide.


  • Correct wrong thickness metadata in PC and PET_G sheet spectra.

Backward incompatibilities

Use of package ‘photobiologyReflectors’, which was never released through CRAN, is deprecated as the same data are now contained in ‘photobiologyFilters’ (>= 5.2).

NOTE: The updated package has been submitted to CRAN.
