Abstract: It comprises optical assemblies that focus light onto individual first optical fibers which are combined together in a final single optical fiber, collecting a considerable amount of light from a target, to feed an instrument such as a spectrograph. The first optical fibers are kept centred on the target through image devices that also provide images, and these images can be combined to give rise to a high-quality image of the field surrounding the target. The final effective aperture of the device is scalable, using different numbers of optical assemblies and depending on their diameters.

Abstract: Temperature effects on results of a lateral flow assay can be compensated for by measuring an environmental temperature at a testing time and a testing location, performing a lateral flow assay at the testing time and testing location to obtain an original concentration value of a target substance, and generating a modified concentration value of the target substance. The modified concentration value is generated based on the original concentration value, by compensating for a difference between the environmental temperature and ambient temperature.

Abstract: A gas analyzer and a corresponding method is provided to measure the concentration of formaldehyde within enclosed environments such as within buildings comprising an ultraviolet light source, a sample chamber, a detector. The detector measures the intensity of light received by photosensors within a measurement range of wavelengths, and at least one reference range of wavelengths. Advantageously, the concentration of formaldehyde is determined taking into account fluctuations in the intensity of light emitted by the light source, and in the presence of any interferents such as nitrogen dioxide.

Abstract: Lighted refrigerated display case with remote light source comprises a closed container with an interior of the container refrigerated to a temperature below 7 C. The container is thermally insulated from ambient, having internal and external walls. A solid fiber optic luminaire is at least partially mounted within the container, having an elongated side-light emitting portion for emitting light from the side of the luminaire onto contents in an interior of the display case. The side-light emitting portion comprises an extractor of light arranged to preferentially extract light from the luminaire and direct the light in at least one radial direction along the length of the side-light emitting portion to at least one target area of said contents along a longitudinal axis of the side-light emitting portion. A light-delivery system provides light to the fiber optic luminaire, having a light source mounted remotely from the interior of the container.

A light-transparent aperture located towards the forward end of the housing. A light-transmitting conduit enters the housing rearwardly of the light-transparent aperture with at least one plate that is mounted to the housing.

The light apertures provide structural reinforcement to the generally forward area of said housing.

Abstract: A luminaire with improved lateral illuminance control comprising a light pipe with a longitudinal center is disclosed. A light-extraction means applied to a radial swath of the light pipe has a longitudinal portion having dimension along its length, centered about a slice on the light pipe longitudinally; said slice being orthogonal to the longitudinal center and located in a propagation plane through which light propagates to a virtual target area intersecting the propagation plane. The light pipe intervenes between the radial swath and the target area. A first average efficiency point of the light-extraction means corresponds to the minimum distance to the target area being at least approximately 20% less than a respective, second average efficiency point corresponding to a respective maximum distance to such area. The light-extraction means efficiency varies from the first average efficiency point to the second average efficiency point though more than one non-zero value.
