    Abstract: A mirror fluorometer (10) with a rotatable mirror (24) positioned such that it is capable of projecting a converging cone of excitation light onto one or more of the samples wherein the fluorescent signals emitted from the fluorophores in the sample (34) is detected. A method of using the mirror fluorometer (10) for detecting fluorescent signals emitted by one or more fluorophores from samples (34) from a natural or industrial water system. The fluorometer (10), when coupled with a controller is capable of monitoring and optionally controlling an industrial process or system, including a paper mill process.

    Abstract: An illumination subsystem for use in optical analysis which provides spatially and angularly homogenized radiation to the sample being analyzed. The system eliminates the illumination system as an interferent in the overall optical analysis. Thus, modest translations or rotations of the illumination source or changing the illumination source does not require recalibration of the instrument or prior modeling of illumination variability due to such changes. Illumination stability is achieved by incorporating a light pipe which both angularly and spatially homogenizes the light. Further, a series of filters and/or lenses are incorporated to provide bandpass filtering which eliminates unwanted wavelengths or bands of wavelengths from contacting the tissue and allows for a higher signal-to-noise ratio when the sample is tissue, while preventing thermal damage.

    Abstract: A curved mirrored surface (78) is used to collect radiation scattered by a sample surface (76a) and originating from a normal illumination beam (70) and an oblique illumination beam (90). The collected radiation is focused to a detector (80). Scattered radiation originating from the normal and oblique illumination beams may be distinguished by employing radiation at two different wavelengths, by intentionally introducing an offset between the spots illuminated by the two beams or by switching the normal and oblique illumination beams (70, 90) on and off alternately. Beam position error caused by change in sample height may be corrected by detecting specular reflection of an oblique illumination beam and changing the direction of illumination in response thereto. Butterfly-shaped spatial filters may be used in conjunction with curved mirror radiation collectors (78) to restrict detection to certain azimuthal angles.

    Abstract: The present invention concerns an LED spectrometer operating without moving parts, according to the sweep principle, and appropriate to serve as a structural component in many kinds of spectroscopic concentration analysers. The design of the invention affords the advantage that, even at its minimum, the optical power of the LED spectrometer of the invention is about fivefold compared with designs of prior art. Furthermore, improvement of the efficiency of the LED radiation source and of that of the optics has brought a multiple augmentation in power to the wavelength spectrum sent out by the radiation source. In the design of the invention, concentrators (6) of non-imaging type are used to collimate the wavelength spectrum emitted by the LEDs (3).

    Abstract: A spectroscopic system for the analysis of small and very small quantities of substances makes use for the purposes of energy transfer of cone-shaped aperture changers (14, 15) which are arranged in the object zone (8) between the light source (L) and the sample (9) and, during absorption measurements, also between the sample (9) and the inlet slot (3) of a spectrometer (1). If the form used is a double cone, the aperture changers (14, 15) facilitate an oblique coupling in a capillary tube accepting the sample (9) which acts as a step-waveguide for the coupled radiation.
