Abstract
A spectroscopic system is provided for light homogenization and spectral analysis. The system includes an illumination using LEDs mounted on an integrating sphere to homogenize input light for consistent illumination profiles across broad wavelength ranges. Reference and sample cuvette holders are optically coupled to the illumination sphere. Light transmitted through the cuvettes enters respective reference and sample integrating spheres where is homogenized and emitted as uniform output light. The cuvette holders have a side opening for side-mounted illumination sources. A reflective background surface can also be provided to reflect light from the side-mounted illumination source into the integrating spheres. A diffraction grating and an imaging capture device resolve and record spectral data. A processor is provided to control illumination parameters (intensity, wavelength), slit adjustment, image capture, and data processing, enabling data analysis. The components are integrally formed as a single unit for compactness and efficiency.
