Product Presentation
JY-QEY6500-PL is a fluorescence quantum efficiency tester independently developed by our company. This system is mainly used for measuring the fluorescence quantum efficiency of materials (solutions, powders, films). The testing system is calibrated using a traceable light source and can accurately measure absolute quantum yield and chromaticity, while also enabling photoluminescence spectrum measurement and recording. Except for replacing the light source and handling samples, all other measurement operations can be completed on the software interface, achieving automated measurement. The system structure is simple and easy to operate. The JY-QEY6500-PL quantum efficiency instrument provides stable, fast, and reliable measurements. Compared with traditional fluorescence spectrometers, the entire system has advantages such as compact size and ease of use. JY-QEY6500 offers a low-cost solution for fluorescence detection and quantum efficiency measurement, suitable for universities and research institutions.
