Edinburgh Instruments, the world's leading manufacturer of modular systems for optical spectroscopy, has introduced the new QYPro integration sphere to enable easy, fast and accurate measurement of photoluminescence quantum yield and spectral reflectance. The QYPro sphere is primarily designed for FLS1000 luminescence spectrometers and can be easily adapted to the chosen spectrometer geometry using interchangeable excitation ports. Thanks to the motorized sample insertion mechanism, the entire sample exchange process is quick and easy, plus the risk of sphere contamination is significantly reduced, which is key to obtaining accurate results.
