    Abstract: PROBLEM TO BE SOLVED: To provide a spectroscope of high wavelength resolution and high space resolution.
    SOLUTION: This spectroscope is provided with an incident slit 12, a collimator lens optical system 14 for bringing light transmitted through the incident slit into parallel light, a reflection type diffraction grating 16 for receiving the parallel light to output the light to a different angle in response to a wavelength, a convergence lens optical system 18 for converging output light from the diffraction grating, and a two-dimensional photoreception means 20 having a two-dimensional photoreception face for detecting converged light by the convergence lens optical system. An optical axis of the collimator lens optical system is arranged to bring an angle 2γ formed with respect to an optical axis of the convergence lens optical system into an acute angle, the convergence lens optical system and the diffraction grating is arranged to make a distance therebetween nearer than a distance between the collimator lens optical system and the diffraction grating, and a normal vector in the central part of a reflection face of the diffraction grating is set to be directed to an arrangement side of the collimator lens optical system, with respect to a bisector of the angle formed by the collimator lens optical system and the convergence lens optical system.

    Abstract: In an example, an Echelle grating wavelength division multiplexing (WDM) device includes a first waveguide, a slab waveguide, multiple second waveguides, an Echelle grating, and a metal-filled trench. The first waveguide includes either an input waveguide or an output waveguide. The multiple second waveguides are optically coupled to the first waveguide through the slab waveguide. The multiple second waveguides include multiple output waveguides if the first waveguide includes the input waveguide or multiple input waveguides if the first waveguide includes the output waveguide. The Echelle grating includes multiple grating teeth formed in the slab waveguide. The metal-filled trench forms a mirror at the grating teeth to reflect incident light from the first waveguide toward the multiple second waveguides or from the multiple second waveguides toward the first waveguide.

    Abstract: A system and method for internally inspecting a tubular composite part so as to identify and measure adhesive flow therewithin are provided, along with an endpoint adapter assembly of a near infrared (NIR) spectrometer. The system includes an end point adapter that fits within and maintains a consistent cross-sectional position within the tubular composite part. The system also includes a plurality of optical fibers extending radially outward from the end point adapter. The end point adapter moves longitudinally through the tubular composite part and receives light with the plurality of optical fibers following interaction of the light with the tubular composite part. The system further includes a NIR imaging spectrometer configured to disperse the light being collected by the plurality of optical fibers across an NIR spectrum and a NIR camera configured to generate images of the tubular composite part based on dispersed light.
