    Abstract: In a spectroscopy module 1, a light passing hole 50 through which a light L1 advancing to a spectroscopic portion 4 passes is formed in a light detecting element 5. Therefore, it is possible to prevent the relative positional relationship between the light passing hole 50 and a light detecting portion 5a of the light detecting element 5 from deviating. Moreover, the light detecting element 5 is bonded to a front plane 2a of a substrate 2 with an optical resin adhesive 63. Thus, it is possible to reduce a stress generated onto the light detecting element 5 due to a thermal expansion difference between the light detecting element 5 and the substrate 2. Additionally, the light transmissive plate 16 covers a part of a light incident opening 50a. Thus, a light incident side surface 63a of the optical resin adhesive 63 becomes a substantially flat plane in the light passing hole 50. Therefore, it is possible to make the light L1 appropriately incident into the substrate 2.

    Abstract: A spectroscopic method and spectroscopy system therefrom for analyzing samples. A sample includes a first chemical component that has a characteristic first absorption peak is provided. The sample is irradiated in a measurement waveband proximate to the first absorption peak, and at a first and a second reference waveband where the first chemical component lacks characteristic absorption features. Reflected or transmitted detection data is obtained including a measured power proximate to the first absorption peak and first and second reference powers at the reference wavebands. A plurality of different waveband ratios are evaluated using pairs of detection data to generate a plurality of measured waveband ratio values. A parameter of the first chemical component is then determined by evaluating a multidimensional polynomial calibration equation that relates the parameter of the first chemical component to the plurality of different waveband ratios by substituting the measured waveband ratio values into the calibration relation.

    Abstract: A method for detecting trace levels of dissolved organic compounds and leached plastic compounds in drinking water includes the steps of employing deep ultraviolet light-emitting diode induced fluorescence at sensitivity levels of several parts per trillion in real time so that a more compact and inexpensive excitation source, relative to a deep UV laser-induced fluorescence, for fluorescence detection of dissolved organic compounds in water is provided. The deep UV light-emitting diode is operated at an excitation near 265 nm and the laser induced fluorescence is detected at an emission near 450 nm to 500 nm for the dissolved organic compounds and near 310 nm for leached plastic compounds. Optical absorption filters and optical bandpass filters are employed to reduce out-of-band light emitting diode emissions and to eliminate second order optical interference signals for the detection of a fluorescence signal near 450 nm to near 500 nm. The system can measure water contained within a quartz optical cell, within bottled water containers, or in a flowing stream of water.

    Abstract: A zoned order sorting filter for a spectrometer in a semiconductor metrology system is disclosed with reduced light dispersion at the zone joints. The order sorting filter comprises optically-transparent layers deposited underneath, or on top of thin-film filter stacks of the order sorting filter zones, wherein the thicknesses of the optically-transparent layers are adjusted such that the total optical lengths traversed by light at a zone joint are substantially equal in zones adjacent the zone joint. A method for wavelength to detector array pixel location calibration of spectrometers is also disclosed, capable of accurately representing the highly localized nonlinearities of the calibration curve in the vicinity of zone joints of an order sorting filter.
