Abstract: Optical computing devices are disclosed. One optical computing device includes an electromagnetic radiation source that emits electromagnetic radiation into an optical train to optically interact with a sample and at least one integrated computational element, the sample being configured to generate optically interacted radiation. A sampling window is arranged adjacent the sample and configured to allow transmission of the electromagnetic radiation therethrough and has one or more surfaces that generate one or more stray signals. A first focal lens is arranged to receive the optically interacted radiation and the one or more stray signals and generate a primary focal point from the optically interacted radiation. A structural element defines a spatial aperture aligned with the primary focal point such that the optically interacted radiation is able to pass therethrough while transmission of the one or more stray signals is substantially blocked by the structural element.

Abstract: An absorption cell for microfluidic chemical analysis made from tinted or coloured polymers, for example polymethylmethacrylate (PMMA), in which microfluidic channels are cut. Light is coupled into the absorption cell via two windows (typically 200 um thick) that are retained at either end of the channel. Absorption is measured using a light source, such as a light emitting diode (LED) and a photodiode butted against the windows. Spurious scattered and/or reflected light is absorbed by the coloured polymer over the length of the measurement cell, while very little light loss occurs at the coupling windows.

Abstract: An annular optical device (100) includes an annular meso-optic (1) including an annulus (11) centered about an axis of revolution (A) and a secondary optical structure (2) substantially coaxial within the annulus (11). The secondary optical structure (2) and the annular meso-optic (1) are separated by a media (12) including a media refractive index that is lower than the refractive index of the secondary optical structure. The secondary optical structure (2) holds a specimen to be radiated by impinging electromagnetic radiation. Scattered radiation from the secondary optical structure (2) and within the annulus (11) of the annular meso-optic (1) is allowed into the annular meso-optic (1) if an angle of incidence of the scattered radiation exceeds a predetermined incidence threshold. The annular meso-optic (1) re-directs the scattered radiation to comprise re-directed radiation that is substantially parallel to the axis of revolution (A).

Abstract: System and method for detecting and counting bacteria suspended in a biological fluid by means of light scattering measurements is provided. In accordance with the method of the invention the level of signal to noise of the measured intensities of light scattered by a sample of the biological fluid is significantly enhanced for forwardly scattered light within a range of scattering angles which are smaller compared to a predefined maximal scattering angle. The system of the invention includes a cuvette adapted to contain a sample of the biological fluid whose sidewalls and windows are suitably constructed and arranged to significantly reduce the level of reflected light obscuring the scattering patterns measured within the range of scattering angles considered.

Abstract: The invention relates to a microelectronic sensor device and a method for making optical examinations at a carrier (11), e.g. for the detection of magnetic particles (1) at a contact surface (12) of the carrier (11) by frustrated total internal reflection (FTIR). A light source (21), particularly a laser light source, with a laser modulator (22) are used for emitting an input light beam (L1) into the carrier (11) which is modulated such that optical interferences with reflections (L1′) of the input light beam (L1) from the entrance window (14) or other components of the carrier (11) are reduced/minimized. This can for example be achieved by a pulsed on/off modulation in which the first relaxation minimum of a currently emitted pulse (PN) coincides in the light source (21) with the first relaxation maximum of a reflected pulse (PN-1′). By reducing the effect of interferences, the setup is less prone to disturbances from dimensional variations that are e.g. induced by thermal extension.
