Abstract: A spectral filter (10) is provided with a long-pass filter (12) and a short-pass filter (13). The long-pass filter (12) has a film thickness gradient GL wherein film thickness increases monotonically in a single direction, and transmits light of a wavelength region longer than a cut-off wavelength WL. The short-pass filter (13) has a film thickness gradient GS wherein film thickness increases monotonically in a single direction, and transmits light of a wavelength region shorter than a cut-off wavelength WS. The long-pass filter (12) and the short-pass filter (13) are overlapped such that the single directions match each other. At the positions in the single directions, a transmittance peak is formed by the cut-off wavelength WL being shorter than the cut-off wavelength WS. The film thickness gradient GL is greater than the film thickness gradient GS.

Abstract: A measuring device is a measuring device that performs colorimetry of an evaluation patch formed on a medium and a paper white patch that is a portion exposed by the medium. The measuring device has a light source portion that irradiates the medium with an illumination light, a measurement portion that acquires an amount of light from the medium as a measurement value, a memory that holds a paper white standard value that is a reference measurement value of the paper white patch, and a colorimetry unit that corrects a measurement value of the evaluation patch based on the measurement value of the paper white patch and the paper white standard value. Even in a case where a measurement position is changed, a reflectance of the evaluation patch is accurately calculated and a chromaticity of the evaluation patch can be accurately acquired.

Abstract: A system for determining a calibrated spectral measurement includes a tunable Fabry-Perot etalon, a detector, and a processor. The tunable Fabry-Perot etalon has a settable gap. The detector measures light intensity transmitted through the tunable Fabry-Perot etalon. The processor is configured to determine the calibrated spectral measurement. The calibrated spectral measurement is based at least in part on a measurement set of detected light intensities for a plurality of settable gaps and a reconstruction matrix. The reconstruction matrix is based at least in part on calibration measurements using multiple source wavelengths and multiple settable gaps.

Abstract: A device analyzes an anesthesia ventilation gas with an infrared radiation source and includes a gas cuvette, a Fabry-Perot interferometer with a band pass filter function, adjustable with respect to a central transmission wavelength as a function of a control signal, a detector providing a measured signal and a computing and control unit providing the control signal and detecting the measured signal. The computing and control unit is configured to actuate the Fabry-Perot interferometer in a first operating mode by the control signal such that the central transmission wavelength scans a predefined wavelength range, to detect a presence in the ventilation gas sample potential types of anesthetic gases based on the measured signal. In a second operating mode, the control unit controls the central transmission wavelength within a subrange of the predefined wavelength range and determines a plurality of concentration values at consecutive times for detected types of anesthetic gases.

Abstract: A compact spectrometer system comprising an improved detector is provided herein. The spectrometer system herein disclosed can comprises a filter, a Fourier transform optical element, and a detector. The detector can comprise a custom detector having a shape that corresponds to the pattern of light incident on the detector. The custom detector may comprise a plurality of separate detection areas, each area configured to detect a portion of the light pattern incident on the detector. The custom detector may comprise a material capable of detecting wavelengths in the short-wavelength infrared (SWIR) range. The custom detector may be configured to require a relatively low number of electrical connections such that it may be implemented using standard, low-cost electronic packaging techniques. An improved, custom detector as described herein can provide the functionality of a two-dimensional pixel array detector while being relatively simple and inexpensive to manufacture.
