Abstract: An optical device for sensing a presence of an analyte in a person is provided. The optical device includes a light source, an optical stack, and a reader. The light source emits a first light having a first wavelength. The optical stack is placed on a skin of the person. The optical stack includes a sensor material and an optical filter. The sensor material emits a second light having a second wavelength when irradiated with the first light. An optical property of the second light is sensitive to the presence of the analyte. The optical filter is disposed on the sensor material and includes a plurality of microlayers numbering at least 10 in total. The optical filter has different first and second transmittances at the respective first and second wavelengths.

Abstract: A transmission spectroscopy device can direct light into a sample, and determine properties of the sample based on how much light emerges from the sample. The device can use a cell to contain the sample, so that the size of the cell defines the optical path length traversed by light in the sample. To ensure accuracy in the measurements, it is beneficial to calibrate the device by measuring the size of the cell periodically or as needed. To measure the size of the cell, the device can perform a transmission spectroscopy measurement of a known substance, such as pure water, to produce a measured absorbance spectrum of the known substance. The device can subtract a known absorbance spectrum of the known substance from the measured absorbance spectrum to form an oscillatory fringe pattern. The device can determine the size of the cell from a period of the fringe pattern.

Abstract: A method and system for testing the functional capability of an analytical instrument uses first and second blind samples. Each blind sample is a test substance with an amount of a parameter to be tested that is unknown to the user. Each blind sample is provided with an identification means with a unique identification. When the blind samples are tested by the user in the instrument being tested, the measurement values obtained and the unique identifications read are compared against predetermined values that are accessible to a test program configured as software on the analytical instrument. By comparison of the measurement values and the predetermined values, the functional capability of the analytical instrument is determined and the result is transmitted to an output unit of the analytical instrument.
