Optical spectroscopic techniques, such as UV-VIS-NIR and Raman, allow for the at-line and in-line, real-time analysis of multiple parameters for process and quality control. The spectrometer systems have been used for reflection measurements in various applications and are easily adapted to different sampling methods including fiber-optic reflection probes and active measuring heads. The sample is illuminated by a continuous, white light source. The reflected light is then measured, allowing the determination of the spectral information as a function of wavelength.
