lentil.radiometry.Material

class lentil.radiometry.Material(transmission=1, emission=0, contam=1)[source]

Class for representing a material with radiometric properties.

Parameters
  • transmission (Spectrum or float, optional) – Spectral transmission. If not specified, a default transmission is created which has no radiometric effect.

  • emission (Spectrum or float, optional) – Spectral thermal emission of the element. If not specified, a default emission is created which has no radiometric contribution.

  • contam (float or Spectrum, optional) – Material contamination factor. Can be used for representing EOL/BOL optical properties. Should be within [0,1]. Both transmission and emission are multiplied by contam before being returned.

Note

There is no explicit reflection attribute. Reflective optics should use the transmission attribute to represent reflectivity.
