According to ISO 21073:2019, co-registration accuracy measures the capacity of a microscope system to image a fluorescent object with different excitation and emission Wavelengths at the same position in the Image. Hence, the spatial distance of the Image positions of a Point-like object (i.e., Spot or Point Emitter) located in the centre of the Field of View (FOV) for different excitation and detection Wavelength bands is denoted as co-registration accuracy. The co-registration accuracy shall be calculated from the Intensity maxima or the Intensity centre of gravity of the Image of the Point-like object for the different Wavelengths. The lateral co-registration accuracy is expressed as: ∆lateral = √(xλ1 - xλ2)^2 + (yλ1 - yλ2)^2; and the axial co-registration accuracy is expressed as: ∆axial = √(zλ1 - zλ2)^2. This element refers to the results of a specific Co-registration Accuracy evaluation assay associated with this Optical Calibration procedure.
