Abstract: A system comprising a calibration light source is described. The system includes a calibration optical fiber coupled to an output of the calibration light source and to an input slit of a spectrometer. The calibration optical fiber transmits light output of the calibration light source to the spectrometer via the slit. An input optical fiber is coupled to the input slit in addition to the calibration optical fiber. The input optical fiber transmits light-under-test to the spectrometer via the slit.

Abstract: Embodiments described herein correct errors in spectrometer outputs due to the presence of second-order light. Embodiments determine a relationship between first-order light and second-order light of the spectrometer output. The relationship is a function of wavelength and an output of the spectrometer due to the first-order light. The relationship is used to determine an estimated contribution of the second-order light to the output. Spectrometer errors introduced by the second-order light are corrected by adjusting the spectrometer output according to the estimated contribution of the second-order light.

Abstract: A system comprising a light source, and a retention device configured to receive and retain a sample for measurement. The system includes a detector. An optical path couples light between the light source, the sample when present, and the detector. An optical objective is configured to couple light from the light source to the sample when present, and couple reflected light to the detector. A controller is configured to automatically control focus and/or beam path of the light directed by the optical objective to the sample when present. The system includes a spatially variable filter (SVF) positioned in the optical path. The SVF is configured to have spectral properties that vary as a function of illuminated position on the SVF.

Abstract: Embodiments include a spectral reflectance system comprising a light source. The system includes a platform configured to retain a sample. The system includes an optical director positioned in the optical path between the light source and the platform. The optical director couples light from the light source to the platform. The system includes a detector positioned to receive reflected light from the sample. The detector generates a signal representing the reflected light. The system includes a focusing system coupled to the optical director. In response to the signal the focusing system automatically focuses the light on the sample by controlling a position of the optical director to maximize a strength of the signal.

Abstract: Embodiments described herein include broadband light source system comprising an optic coupler including a plurality of input branches coupled to an output. The system includes a plurality of light sources coupled to the plurality of input branches. Each light source outputs light having a different wavelength distribution than any other light source of the plurality of light sources. The output emits a broadband light source comprising a combined spectral output of the plurality of light sources.
