Abstract: A wavelength of incident light is measured based on signals from a plurality of pixels of a photoelectric conversion element that are arranged in a dispersion direction in which the incident light is dispersed by a spectroscopic section. In correction of a shift in wavelength, a measured amount of shift in wavelength that is a difference between a measured value obtained when an emission line wavelength of incident light from a light source for wavelength shift correction that emits light including an emission line at least one wavelength in a range of wavelengths into which light can be dispersed by the spectroscopic section is measured and an original emission line wavelength is calculated. A reference amount of shift in emission line wavelength is calculated by a polynomial in which a characteristic of a wavelength shift that occurs is represented by a linear or higher polynomial with a variable indicating the wavelength or a parameter relating to the wavelength. Each coefficient of the polynomial is determined based on the calculated measured amount of shift in emission line wavelength and the reference amount of shift in emission line wavelength, and the wavelength of the incident light is corrected based on the determined polynomial.

Abstract: A spectroscopic metrology system includes a spectroscopic metrology tool and a controller. The controller generates a model of a multilayer grating including two or more layers, the model including geometric parameters indicative of a geometry of a test layer of the multilayer grating and dispersion parameters indicative of a dispersion of the test layer. The controller further receives a spectroscopic signal of a fabricated multilayer grating corresponding to the modeled multilayer grating from the spectroscopic metrology tool. The controller further determines values of the one or more parameters of the modeled multilayer grating providing a simulated spectroscopic signal corresponding to the measured spectroscopic signal within a selected tolerance. The controller further predicts a bandgap of the test layer of the fabricated multilayer grating based on the determined values of the one or more parameters of the test layer of the fabricated structure.

Abstract: An optical metrology device performs multi-wavelength polarized confocal Raman spectroscopy. The optical metrology device uses a first light source to produce a first light beam with a first wavelength and a second light source to produce a second light beam with a second wavelength. A dichroic beam splitter partially reflects the first light beam and transmits the second light beam to combine the light beams along a same optical axis that is incident on a sample. The dichroic beam splitter directs the Raman response emitted from the sample in response to the first light beam and the second light beam together towards at least one spectrometer and directs the first light beam away from the at least one spectrometer. A chopper may be used to isolate the Raman response to the first and second light beams that is received and spectrally measured by the at least one spectrometer.

Abstract: The invention discloses a design method of a wavenumber linearity dispersion optical system and an imaging spectrometer, including: building an optical system including a grating, a prism and an objective lens that are sequentially arranged, the grating adjoins the prism; defining a linearity evaluation coefficient RMS; assigning a minimum value to the linearity evaluation coefficient RMS through adjustment to the vertex angle of the prism, when the linearity evaluation coefficient RMS is at minimum, the vertex angle of the prism being α1; acquiring compensations for distortion and longitudinal chromatic aberration of the objective lens based on the interval between equal-difference wavenumbers on the image plane when the vertex angle of the prism is α1; and optimizing the objective lens based on the compensations for distortion and longitudinal chromatic aberration of the objective lens to obtain an optimized optical system. Higher wavenumber linearity can be achieved through objective-lens-aberration compensated wavenumber linearity.
