Fluorescence measurements are a staple in biomedicine, from research and discovery to more recently, for fluorescenceguided imaging systems for diagnostics and surgery. Measurement validation for clinical imagers is a challenge as it is applied to many different optical systems and probe through matrices with different optical properties in a demanding field environment. In this paper we will present approaches to fluorescence calibration for a field system, in comparison to those used in laboratory instruments for cell measurements or benchtop fluorometers. We will present the common challenges and differences, and lessons from the standardization effort of laboratory fluorescence measurements. We will discuss the conceptually different pathways to measurement traceability, between counting moles of substance and measuring light.
