Abstract: An optical assembly 140 for a portable device for detecting molecule(s) within reaction vessels 110 comprises a collimator 403, a beam splitter arrangement and a plurality of guide arrangements 143. The collimator 403 collimates an excitation beam from an excitation source 400. The beam splitter arrangement splits the excitation beam from the collimator into a plurality of split excitation beams. Each beam splitter splits an incoming beam into two beams. In the case where the beam splitter arrangement comprises more than one beam splitter, the beam splitters are arranged in tiers such that a first tier comprises one beam splitter for receiving the excitation beam from the collimator, and each of the other tiers comprises one or more beam splitters. Each beam splitter in at least one of the other tiers receives a split excitation beam from a previous tier. Each guide arrangement 140 guides a respective one of the plurality of split excitation beams along an excitation path A from the beam splitter arrangement into a reaction vessel 110 containing a sample to stimulate an emission of a reaction light from the sample. Each guide arrangement 140 further guides reaction light from the sample along a detection path B towards a detector arrangement 142.

Abstract: The present invention provides systems and methods for analyzing the excitation spectra of fluorescent particles in a flowing stream. The system uses a white light laser and color separation optics to provide a spatially-distributed, continuous color-spectrum excitation light system that is used to illuminate a region of a flowing stream. A particle that passes through the detection region traverses the full dispersed spectrum of excitation light, and the fluorescence emissions from the particle are continuously measured as it passes through the detection region. The measured fluorescence emissions at each wavelength of excitation light, which changes through full spectrum of the excitation light as the particle passes through the detection region, provides the excitation spectrum of the particle.

Abstract: Devices and methods are disclosed for characterizing point flaws (including pinholes and point defects) of an optical filter. A passband test is performed, including: illuminating the optical filter with passband illumination whose spectral range at least overlaps a passband of the optical filter; acquiring a passband map of the optical filter using a two-dimensional array of photodetectors while illuminating the optical filter with the passband illumination; and identifying point defects of the optical filter as low intensity locations of the passband map. A stopband test is performed, including: illuminating the optical filter with stopband illumination whose spectral range lies entirely outside of the passband of the optical filter; acquiring a stopband map of the optical filter using the two-dimensional array of photodetectors while illuminating the optical filter with the stopband illumination; and identifying pinholes of the optical filter as high intensity locations of the stopband map.
