Abstract: A water quality sensor includes a light source, a beam splitter, a first detector, a second detector, and a measurement space. The beam splitter splits light emitted from the light source into transmitted light and reflected light. The first detector detects the transmitted light. The second detector detects the reflected light. The measurement space is filled with a sample of liquid. Of an optical path along which light propagates from the light source to the first detector, a portion extending through the measurement space is defined as a first optical path. Of an optical path along which light propagates from the light source to the second detector, a portion extending through the measurement space is defined as a second optical path. The optical path length of the second optical path differs from the optical path length of the first optical path.

Abstract: Device for improving an optical detecting smoke apparatus and implementing thereof. Apparatus and methods for detecting the presence of smoke in a small, long-lasting smoke detector are disclosed. Specifically, the present disclosure shows how to build one or more optimized blocking members in a smoke detector to augment signal to noise ratio. This is performed while keeping the reflections from the housing structure to a very low value while satisfying all the other peripheral needs of fast response to smoke and preventing ambient light. This allows very small measurements of light scattering of the smoke particles to be reliable in a device resistant to the negative effects of dust. In particular, geometrical optical elements, e.g., cap and optical defection elements, are disclosed.

Abstract: A method is used to determine an absorption behavior of a medium. The method includes establishing an absorption coefficient of the medium using a first intensity value and at least one second intensity value and a length different between a first measurement distance and a second measurement distance. The first intensity value represents a measured first light intensity after passing over a first measurement distance in the medium. The second intensity value represents a measured second light intensity after passing over a second measurement distance in the medium. The first intensity value and the second intensity value are measured using light with a common initial intensity.

Abstract: A device for analyzing immunoassays with a liquid assay medium includes a vessel for holding the assay medium. The vessel has a base comprised of a solid body having a first side wall and a top surface forming a boundary surface of the solid body. First reaction agents are dissolved in the assay medium in the vessel and are labeled with a luminophore or different luminophores and second reaction agents are bonded to the boundary surface within a boundary layer of the assay medium. A transmitter for emitting light rays is arranged so that the light rays are coupled into the base of the vessel via the first side wall and conducted at the total reflection angle to the boundary surface so that luminophore-labeled first reaction agents that are bonded to the second reaction agents are optically excited by at least some of the light rays and emit fluorescent and/or phosphorescent rays. A receiver is positioned for quantitatively detecting the fluorescent rays and/or phosphorescent rays.
