influx geometry

irradiation geometry

incidence geometry

angular distribution of the radiation incident on the sample being measured with respect to the centre of the sampling aperture

Note 1 to entry: The influx geometry and efflux geometry together specify the geometric nature of the measurement for reflectance and transmittance measurements.

Note 2 to entry: This entry was numbered 17-577, 17-611, and 17-571 in CIE S 017:2011.
