Abstract: In a first aspect, the invention relates to a photoacoustic gas sensor comprising a gas-fillable detection chamber and a reference chamber arranged laterally adjacent to each other and connected by a sensor channel. A sensor located at or in the sensor channel allows measurement of the photoacoustic signals. Both chambers are preferably located in a plane perpendicular to the emitted IR radiation of the IR emitter which is also comprised. The gas sensor is also formed from a multilayer substrate.
In further aspects, the invention also relates to a method of manufacturing a gas sensor and a method of analyzing gas with a gas sensor.

Abstract: Presently disclosed is a lighting system and methods of using the lighting system for in vitro potency assay for photofrin. The lighting system includes a lamp housing, a first lens, an infrared absorbing filter, an optical filter, and a second lens. The lamp housing includes a lamp and a light-port. In operation, broad spectrum light from the lamp exits the lamp housing by passing through the light-port. The first lens then collimates the broad spectrum light that exits the lamp housing through the light-port. The infrared absorbing filter then passes a first portion of the collimated broad spectrum light to the optical filter and absorbs infrared light of the broad spectrum light. The optical filter then passes a second portion of the collimated broad spectrum light to the second lens. The second lens then disperses the second portion of the collimated light to provide uniform irradiation of a cell culture plate. A method of using the lighting system for studying a photosensitizer is also disclosed.

Abstract: A device (1) for determining the concentration of a gas component is configured with a radiation source (30) for emitting (31) a light radiation or heat radiation in an infrared wavelength range. A detector array (40) has at least two detector elements (50, 60), configured to detect the radiation generated by the radiation source (30), in an angular arrangement (52, 62) and with filter elements (51, 61). At least one of the two detector elements (50, 60) is oriented in an angular arrangement (52, 62) in relation to a vertical axis (32), so that a range of overlap (65) is obtained due to the angular arrangements (52, 62). The range of overlap (65) causes attenuations in the propagation of light, which attenuations may be due, for example, to gas molecules or moisture (400), affect both detector elements (50, 60) and are thus compensated concerning the concentration determination.

Abstract: A gas concentration measurement device measures a gas concentration based on an absorbance of sample gas in a region between a light source that emits infrared light and a detector that detects the infrared light. The gas concentration measurement device includes a rotating member, first and second band pass filters on the rotating member, and a rotational driver. The first and second band pass filters are located on a pair of planes that intersect each other. The rotational driver rotates the rotating member around the rotating shaft to switch between a first state, in which the infrared light from the light source is transmitted through the first band pass filter, and a second state, in which the infrared light from the light source is transmitted through the second band pass filter.

Abstract: An apparatus is provided for simultaneously measuring interior temperature and fine dust in a vehicle. The apparatus measures interior temperature of a vehicle and fine dust in the air simultaneously by controlling flow rate of the interior air through a structure for changing air flow rate and making a division between a temperature sensing region and a dust sensing region based on a flow rate difference that occurs based on the structure for changing air flow rate.
