Remote Fluorescent Measurement using FP-8500 Fluorometer with Optical Fiber

A fluorometer with optical fiber can be used for a variety of measurements, such as when the sample is larger than the sample chamber, to follow an in-situ reaction, or for measurement in hazardous environments, such as high/low temperature and high pressure.

Quantum Yield Measurement of the Up-Conversion Phosphors

Quantum yield is very useful in determining the efficiency of multi-step up-conversion excitation process that results in fluorescence at shorter wavelengths than the excitation light. Molecules can be excited at longer wavelengths where light scattering and absorption do not occur.
