Abstract: The present invention relates to improvement in accuracy of an automatic sample detection technique in spectrometry of a microspectroscope.A microspectroscope 10 comprises: a light source 12 that emits an excitation light to a sample 20; a condensing lens 16 that emits the excitation light to a predetermined position of the sample 20 and condenses a reflected light or a transmitted light from the sample 20; a spectrometer 24 that detects a condensed light; and an analysis control unit 30 for analyzing a signal from the spectrometer 24; the microspectroscope 10 that uses an observation image of the sample 20 to perform spectrometry, wherein the analysis control unit 30 comprises: an image storage part 32 that converts the observation image to an all-in-focus image to store the all-in-focus image; and a control part 34 that makes the microspectroscope 10 to perform measurement, the image storage part 32 adds a detected information of a sample point that is a target of spectrometry to the all-in-focus image to create a sample search image data, and the control part 34 automatically detects the sample point by using the sample search image data.

Abstract: An Attenuated total reflection measuring apparatus capable of Raman spectral measurement has an infrared optical instrument and a Raman module. The infrared optical instrument is disposed on an ATR prism side of a sample, and is provided to irradiate the ATR prism with an infrared light, and collect the infrared light from the ATR prism. The Raman module is disposed on a side opposite to the ATR prism side relative to the sample, and has a guide tube that outputs an excitation light from an excitation light source to the sample, and a lens portion disposed inside thereof. An end of the guide tube is in a position to push the sample to the ATR prism. The Raman module has a lens position adjustment mechanism that moves the lens portion along an optical axis, and a spectroscope that detects a Raman scattering light collected by the lens portion.

Abstract: A method of analyzing foreign matter in a sample includes: measuring an optical spectrum for each of a plurality of measurement points of a measurement region on the sample by a microscopic spectroscope; calculating a feature value of each measured spectrum by a computer; determining whether each of the measurement points is on the foreign matter or not based on each feature value; retaining the spectrum of the measurement point that is determined to be on the foreign matter, and deleting the spectrum of the measurement point that is not determined to be on the foreign matter or storing the same to a storage unit; and executing multivariate analysis of the spectra of the plurality of the measurement points that are determined to be on the foreign matter or classifying the same with AI search.
