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 provided scanner includes a source module (113) 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. UV, visible, mid-IR, and IR). The scanner also includes a detection module. Within the detection module (115) are two detectors, thus allowing the simultaneous detection of multiple wavelengths. A bifurcated optical cable (111) is used to transfer the excitation and/or readout light from the source module to the sample and subsequently transfer the emitted and/or scattered light from the sample to the detection module.
