| Zusammenfassung | The LIS-A2 is a novel LED-based transfer standard source for spectral irradiance in the visible range (360-830 nm), which was developed as part of the EMPIR project NEWSTAND. The device in question combines ten phosphor-converted broadband LEDs with five UV LEDs (365-405 nm) to generate a virtually flat spectrum. Integrated temperature stabilisation is crucial to ensure the stability of the emitted light. Compared to halogen lamps, LIS-A2 minimises stray light effects in spectroradiometers due to the significantly lower emission in the IR. Furthermore, the change in the emitted spectrum due to ageing effects during operation is lower. |
