Abstract: A printer that incorporates a spectrometry device includes a spectroscope, a distance measurer, and a spectrometry unit. The spectroscope includes a wavelength-selective interference filter on which light from a position of measurement in a medium is incident. The distance measurer measures the distance between the position of measurement and the spectroscope, and the spectrometry unit performs spectrometry at the position of measurement by using the spectroscope and correct a measured value obtained by the spectrometry based on the measured distance.

Abstract: The invention provides methods and apparatus comprising a multi-wavelength laser source that uses a single unfocused pulse of a low intensity but high power laser over a large sample area to collect Raman scattered collimated light, which is then Rayleigh filtered and focused using a singlet lens into a stacked fiber bundle connected to a customized spectrograph, which separates the individual spectra from the scattered wavelengths using a hybrid diffraction grating for collection onto spectra-specific sections of an array photodetector to measure spectral intensity and thereby identify one or more compounds in the sample.
