Abstract: An optical measurement system, the optical measurement system comprises optics, wherein the optics include a collection path and an illumination path and an objective lens. The optics is configured to acquire Raman spectrums of one or more structural elements located at a measurement site of the sample while being set-up to apply one or more optics parameters that comprise an illumination angle out of a set of multiple illumination angles that correspond to a numerical aperture of the objective lens. Each of the one or more structural elements has a dimension that ranges between one tenth of nanometer to one hundred microns; an optical spectrometer; a Raman detector that is downstream to the optical spectrometer; and a control unit that is configured to determine an expected radiation pattern to be detected by the Raman detector when the optics are set-up to apply the one or more optics parameters.

Abstract: A dual optical frequency comb light-emitting device includes a first optical-frequency-comb laser source that includes a first laser resonator having a first optical path length, a second optical-frequency-comb laser source that includes a second laser resonator having a second optical path length different from the first optical path length, and an optical coupler that causes a first portion of first optical-frequency-comb laser light emitted from the first laser resonator to enter the second laser resonator. The first optical-frequency-comb laser source outputs a second portion of the first optical-frequency-comb laser light to an outside. The second optical-frequency-comb laser source outputs second optical-frequency-comb laser light emitted from the second laser resonator to the outside.

Abstract: Systems and methods for hyperspectral and multispectral imaging are disclosed. A system includes a lens and an imaging device having a plurality of pixel sensors. A focus corrector is located within the optical path to refract at least a portion of the incoming light and change the focusing distance of specific wavelengths of light to converge at a focal plane. The focus corrector is selected based upon the imaging system to reduce an overall measure of deviation between a focal length curve for the lens and a focus position curve for pixel sensors to produce focused imaging data for a broad spectrum of light, including beyond the visible range.
