    Abstract: This invention relates to a light delivery and collection device for measuring Raman scattering from a large area of a sample. The light delivery and collection device comprises a reflective cavity made of a material or having a surface coating with high reflectivity to the excitation light and the Raman scattered light. The reflective cavity has two apertures. The first aperture is configured to receive the excitation light which then projects onto the second aperture. The second aperture is configured to be applied close to the sample such that the reflective cavity substantially forms an enclosure covering a large area of the sample. The excitation light produces Raman scattered light from the covered area of the sample. The reflective cavity reflects any excitation light and Raman light scattered from the sample unless the excitation light and the Raman scattered light either emit from the first aperture to be measured with a spectrometer device, or are re-scattered by the sample at the second aperture. The multi-reflection of the reflective cavity greatly improves the excitation efficiency of Raman scattering from the sample and in the meantime enhances its collection efficiency. In addition, it also causes more excitation light to penetrate into a diffusely scattering sample and allows efficient collection of the Raman scattered light generated thereof, hence enabling sub-surface Raman scattering measurement.

    Abstract: A spectroscopic measurement apparatus includes a light source, an integrator, a first spectroscopic detector, a second spectroscopic detector, and an analysis unit. The integrator includes an internal space in which a measurement object is disposed, a light input portion for inputting light to the internal space, a light output portion for outputting light from the internal space, and a sample attachment portion for attaching the measurement object. The first spectroscopic detector receives the light output from the integrator, disperses the light of a first wavelength region, and acquires first spectrum data. The second spectroscopic detector receives the light output from the integrator, disperses the light of a second wavelength region, and acquires second spectrum data. The first wavelength region and the second wavelength region include a wavelength region partially overlapping each other.

    Abstract: The present invention is directed to an apparatus and method for measuring the haze value of transmissive samples. The apparatus comprises a first light source selectively configurable to emit a first light beam, a second light source selectively configurable to emit a second light beam, an integrating sphere having an outer surface and an inner surface, the inner surface configured to reflect light incident upon the inner surface, the inner surface further enclosing an interior volume. The integrating sphere is further equipped with an exit port configured to emit light from the interior volume of the integrating sphere. The exit port is positioned such that light from the first light source exits the integrating sphere without obstruction, and light from the second light source is diffused on the interior surface of the integrating sphere prior to exiting the exit port. A light detector is also included and is configured to generate a light-intensity signal when light exiting the integrating sphere has passed through a sample and is incident on the light detector. The apparatus further includes a processor configured to receive the light-intensity signal and generate an output signal to a user indicating the haze value. The present invention is also directed to a method of calculating the haze value of a sample using a stored calibration value, a diffuse transmission value (sample-absent diffuse light-intensity value), a direct transmission value (sample-absent direct light-intensity value), a measured diffuse transmission value (sample-present diffuse light-intensity value) and a measured direct transmission value (sample-present direct light-intensity value).
