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.

Abstract: A correlation spectrometer can detect a large number of gaseous compounds, or chemical species, with a species-specific mask wheel. In this mode, the spectrometer is optimized for the direct measurement of individual target compounds. Additionally, the spectrometer can measure the transmission spectrum from a given sample of gas. In this mode, infrared light is passed through a gas sample and the infrared transmission signature of the gasses present is recorded and measured using Hadamard encoding techniques. The spectrometer can detect the transmission or emission spectra in any system where multiple species are present in a generally known volume.

Abstract: An optical slit comprises two blades 40,42 which define a slit between them, each blade being independently movable. This enables both the slit position and the slit width to be adjusted. The slit may be aligned with the center of a light beam by aiming the light beam at a detector, traversing at least one edge of the slit across the beam path, measuring the intensity of transmitted light at the detector for each position of the slit, and feeding back a signal which adjusts the slit position for maximum light throughput. The width on the optical slit may be selected by placing the slit in the path of the light beam and measuring the light transmitted at the detector, calculating the percentage of light transmitted for that slit width and feeding back a signal which adjusts slit width to obtain the desired amount of light throughput.

Abstract: The present invention is directed to apparatus and method for measuring the spectral characteristics of an object surface. The apparatus comprises a light source for generating an input signal comprising a plurality of wavelengths of energy and a diffraction grating for diffracting the input signal into a plurality of diffracted wavelengths of energy. A resonant mirror assembly associated with the diffraction grating sequentially directs a select diffracted wavelength to the object surface to generate a corresponding reflected wavelength of energy. The apparatus further comprises a sensor for determining each select diffracted wavelength of energy directed to the object surface and a detector for detecting one or more of the reflected wavelengths. The detector is coupled with the sensor for associating each select diffracted wavelength with each corresponding reflected wavelength.
