Abstract
Some embodiments of the invention provide an apparatus for measuring active fluorescence in liquid samples by using solid-state components. The use of solid-state devices dramatically lowers the cost, size, and power consumption of active fluorescence while improving the ruggedness and reliability. The smaller size of the solid-state devices allows them to be placed very close to the sample. This maximizes the amount of light the sample receives from the light sources and allows efficient collection of the resulting emitted light using simple and low cost optical components.
