Abstract:
An apparatus capable of measuring quantities of biological or other types of samples that have been labeled using any of a variety of techniques including fluorescence, radioisotopes, enzyme activated light emitting chemicals, and enzyme activated fluorescent materials is provided. The apparatus allows for either simultaneous or sequential acquisition of signals from multiple sample types. The apparatus is not restricted to a particular source or wavelength of excitation or readout light, nor is the apparatus restricted to a particular emission wavelength. The provided scanner includes a source module that preferably contains an internal laser emitting two different wavelengths of approximately the same intensity. An optional external light source may be coupled to the source module, thus adding further flexibility through the addition of other wavelengths (e. g. , V, visible, mid-IR, and IR).
