Abstract: A laser device connectable to an exposure apparatus includes a spectrometer configured to generate a measurement waveform from an interference pattern of laser light output from the laser device; and a processor configured to calculate a first spectral waveform indicating a relationship between a wavelength and a light intensity using the measurement waveform, calculate a representative waveform included in a wavelength range of the first spectral waveform, and calculate an evaluation value of the first spectral waveform using a first integration value obtained by integrating, over the wavelength range, a product of a function of a wavelength deviation from the representative wavelength and the light intensity.

Abstract: Described herein is a wavelength reference device comprising a housing defining an internal environment having a known temperature. A broadband optical source is disposed within the housing and configured to emit an optical signal along an optical path. The optical signal has optical power within a wavelength band of interest. An optical etalon is also disposed within the housing and positioned in the optical path to filter the optical signal to define a filtered optical signal that includes one or more reference spectral features having a known wavelength at the known temperature. The device also includes an optical output for outputting the filtered optical signal.

Abstract: An optical device includes: a base that includes a main surface; a movable unit that includes an optical function unit; and an elastic support unit that is connected between the base and the movable unit, and supports the movable unit so that the movable unit is movable along a first direction perpendicular to the main surface. The elastic support unit includes a lever, a first torsion support portion that extends along a second direction perpendicular to the first direction and is connected between the lever and the movable unit, and a second torsion support portion that extends along the second direction and is connected between the lever and the base. A torsional spring constant of the first torsion support portion is greater than a torsional spring constant of the second torsion support portion.

Abstract: A method for fabrication of a composite component, e.g. wind turbine blade, comprises forming a composite structure within a mold, the composite structure including a resin dispersed throughout the fibers in the composite structure and applying a surface treatment, e.g. sanding, to at least one region of the composite structure. A Fourier Transform Infrared (FTIR) spectrometer is employed to irradiate the treated surface area with infrared light; and determining the amount of infrared light absorbed in the treated area of the composite structure to measure the chemical bond (distribution efficacy, chemical composition, and cure state) of the composite product. Calibration models for a variety of materials are made using a partial least squares 2-variable regression. These calibration files incorporate spectrum from samples of varying resin-hardener mix ratio, and at varying degree of cure. After library comparison confirms the material, the device automatically selects the correct calibration file, ensuring accurate results.
