Radiometry (lentil.radiometry)

radiometry.Spectrum(wave, value[, waveunit, ...])	Class for representing spectral quantities.
radiometry.Blackbody(wave, temp[, waveunit, ...])	Class for representing a blackbody emitter.
radiometry.Material([transmission, ...])	Class for representing a material with radiometric properties.

Utilities

radiometry.path_emission(iterable[, emission])	Construct a common emission from an iterable of Material objects
radiometry.planck_radiance(wave, temp[, ...])	Compute the Planck law spectral radiance from a blackbody radiator at the given temperature.
radiometry.planck_exitance(wave, temp[, ...])	Compute the Planck law spectral exitance from a blackbody radiator at the given temperature.
radiometry.vegaflux(band[, waveunit, valueunit])	Get the flux of Vega in a desired observing band.
