| Zusammenfassung | Knowledge of the spectral irradiance responsivity of photometers over the whole photometric spectral range with lowest uncertainties is important not only for their classification in terms of the spectral match quality index f1' but also for their use in applications requiring a spectral mismatch correction, such as dealing with narrow-band LEDs. Two approaches to such measurements are utilised in this study. They are based on tuneable cw-lasers and on a classical monochromator setup with a microlensarray beam homogenising system. Comparison of the measurement results for different photometers identifies the current limits of the determination of f1' values and the achievable associated uncertainties.
