Some spectrometers will give illuminant values in units of irradiance
(),
but physiological models require illuminants in units of photon (quantum) flux
().
The functions irrad2flux()
and flux2irrad()
allows for easy conversion of
rspec
objects between these units.
irrad2flux(rspecdata)flux2irrad(rspecdata)
(required) a rspec object containing illuminant values.
a converted rspec
object.
