Abstract
A wavelength scanning apparatus that detects at least four different fluorescent emission wavelengths simultaneously or nearly simultaneously is described. The wavelength scanning apparatus includes a heating block having at least four sample wells, each sample well configured for receiving a sample, at least four excitation activation apertures, and at least four fluorescence emission discharge apertures. The wavelength scanning apparatus also includes an analysis scanner having at least four light sources, where the at least four light sources excite at least four fluorophores, at least four excitation light filters that filter out light except that of the desired excitation wavelength/s, at least four fluorescence emission light filters that filter out light except that of the desired fluorescent emission wavelengths, and at least four photodetectors to detect light of the desired fluorescent emission wavelengths.
