    • An absorption spectroscopy apparatus including a sample cell having a central axis, and a side wall coaxially positioned about the axis. The side wall defines a generally circular cross-section of the cell as taken along a plane extending perpendicular to the axis, wherein the generally circular cross-section of the sample cell has an average radius. The side wall includes a plurality of light reflective segments arrayed about the axis, wherein each reflective segment has a cross-section taken along a plane extending perpendicular to the axis of the cell that is concave with respect to the axis. The concave cross-section of each segment has an average radius that is unequal to the average radius of the generally circular cross-section of the sample cell. Among other aspects and advantages, the apparatus of the present disclosure is able to use incoherent, non-collimated light sources while maintaining high optical throughput efficiencies.
    • 一种吸收光谱仪,包括具有中心轴的样品池和围绕轴线同轴定位的侧壁。 侧壁限定了沿着垂直于轴线延伸的平面截取的电池的大致圆形横截面,其中样品池的大致圆形横截面具有平均半径。 所述侧壁包括围绕所述轴线排列的多个光反射段,其中每个反射段具有垂直于所述单元轴线延伸的平面截取的横截面,该平面相对于所述轴线是凹的。 每个段的凹截面的平均半径不等于样品池的大致圆形横截面的平均半径。 除了其它方面和优点之外,本公开的装置能够使用非相干的非准直光源,同时保持高的光通量效率。

    • Methods and apparatus for providing a tunable absorption-emission band in a wavelength selective device are disclosed. A device for selectively absorbing incident electromagnetic radiation includes an electrically conductive surface layer including an arrangement of multiple surface elements. The surface layer is disposed at a nonzero height above a continuous electrically conductive layer. An electrically isolating intermediate layer defines a first surface that is in communication with the electrically conductive surface layer. The continuous electrically conductive backing layer is provided in communication with a second surface of the electrically isolating intermediate layer. When combined with an infrared source, the wavelength selective device emits infrared radiation in at least one narrow band determined by a resonance of the device. In some embodiments, the device includes a control feature that allows the resonance to be selectively modified. The device has broad applications including gas detection devices and infrared imaging.

    • A refrigerator is adapted to include a plurality of ultraviolet light bars, which may be adjustably connected to sufficiently radiate UV light throughout the refrigerator compartment in connection with a control box and power cord which operate to control the bacterial level present on and around foodstuffs being stored therein. A series of UV light bars are capable of being arranged and plugged into one another by daisy chain to allow for a timer-controlled illumination of UV light to radiate throughout the compartment. Sensors in the control box signal the timer, and a wire ribbon extending from the control box provides a connection to the external power source without significantly affecting the seal of the refrigerator door. Power is supplied to the UV light sources via a ribbon-type power cable passing from the refrigerator interior compartment to the exterior by passing between the refrigerator and the refrigerator door and over the peripheral gasket, whereby power may be supplied to said control box by connection of said male electrical plug to an electrical outlet without significantly affecting the integrity of the thermal seal.
