As a concrete example of the invention, radiation, light and radiation detection, including the temporal mode, for example, for a variety of methods and types. Specific examples of such modes, including instant signal, instantaneous stainless steel pipe, time integrated partial signal, time integrated, continuous whole signal, frequency modulated signals or other variations or combinations of these timeaveraged. temporal mode excitation light illumination and detection method related to ofspatial lighting, fluorescent emission of reactive, Waveguide geometry, the desired number of analytes, the sensitivity and the analyte concentration to be determined by the level of steel tube. Excitation light source emission of each sample throughout the whole period of the analyte detection reagent can be hit on. Excitation light source or ambient light can be modulated attempt to eliminate the chopped.

Such an amplifier, then reduce the background interference of the emitted signal demodulation as a lock. optical isolation or protection if the ambient light is eliminated by the modulation of this kind, may not be necessary. One way or the excitation light source, a large common area lighting for stainless steel pipe, and one or more aspects illuminate the entire sample. The advantages of this method include unfocused or diffuse lighting: lighting the fields may be larger than the sample size, because the compliance process, minimizing the extent illuminating the entire sample. One or more excitation light sources and / or to provide light at different wavelengths in order to provide different spatial and temporal coverage, or can be used at the same time.
