Abstract: A cylindrical illumination confocal spectroscopy system has a fluidic device having a fluid channel defined therein, an objective lens unit arranged proximate the fluidic device, an illumination system in optical communication with the objective lens unit to provide light to illuminate a sample through the objective lens unit, and a detection system in optical communication with the objective lens unit to receive at least a portion of light that passes through the objective lens unit from the sample. The illumination system includes a beam-shaping lens unit constructed and arranged to provide a substantially planar illumination beam that subtends across, and is longer than, a lateral dimension of the fluid channel, the substantially planar illumination beam having a diffraction limited thickness in a direction substantially orthogonal to the lateral dimension of the fluid channel. The substantially planar illumination beam incident upon the fluidic device has a width that is substantially longer than the lateral dimension of the fluid channel such that the substantially planar illumination beam has an illumination intensity that is uniform across the lateral dimension of the fluid channel to within ±10%. The detection system comprises an aperture stop defining a substantially rectangular aperture having a longitudinal dimension and a transverse dimension. The aperture stop is arranged so that the substantially rectangular aperture is confocal with an illuminated portion of the fluid channel such that the transverse dimension of the substantially rectangular aperture substantially subtends the lateral dimension of the fluid channel without extending substantially beyond the fluid channel and allows light to pass from only a uniform excitation region while occluding light from outside the uniform excitation region, and the lateral dimension of the substantially rectangular aperture substantially matches the diffraction limited thickness of the planar illumination beam.
