Abstract: This invention addresses the abovementioned problem, and the purpose of this invention is to provide a far-infrared spectroscopy device that uses an is-TPG method to generate far-infrared light, and is capable of efficiently detecting is-TPG light without a detection optical system being fine-tuned. Even if the far-infrared light incidence angles on an Si prism for detection are the same when far-infrared light having a first frequency is incident on a non-linear optical crystal for detection and when far-infrared light having a second frequency is incident on the non-linear optical crystal for detection, this far-infrared spectroscopy device adjusts the incidence surface angle of pump light in relation to the non-linear optical crystal for detection such that the angle of the far-infrared light in relation to the pump light within the non-linear optical crystal for detection can be appropriately set for each far-infrared light frequency (see FIG. 1A).

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: 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.
