Abstract: This Good Practice Guide deals with the estimation of measurement uncertainties for measurements of luminances and luminance distributions using Imaging Luminance Measurement Devices (ILMD) to enable traceable measurements. The first part of this guide covers the uncertainty contributions originating from the ILMD itself. In photometry it is a common approach to determine correction functions for different systematic error contributions and use these functions to correct for these errors. The document explains the problems that may arise when this approach is applied to ILMDs, especially in the context of very limited knowledge on device internals. From this, a reduced approach is derived and examples for the required characterizations are given. The second part covers uncertainty contributions that originate from the scene or the device under test.
