QY-2000 integrating sphere fluorescence spectrometer

Product Introduction
The system is available in a number of international test methods and tools , based on research , quantitative test for fluorescence spectroscopy luminous powder , the data include: the emission spectrum , the external quantum efficiency , absolute ( within ) quantum efficiency, color coordinates, color purity and color temperature CRI . Excellent operability and data reproducibility.

Wherein , the external quantum yield can be used as alternative measurements of the relative fluorescence intensity measurement , the standard sample does not depend on the absolute test , can also be used as a means to monitor the standard sample tested and identified .
Other solid fluorescence test applications , such as napkins fluorescein qualitative and quantitative tests , but also provides a simple and reliable method for rapid detection of rapid quality health system .
