摘要： A collection optics system for a spectrometer and a Raman spectral system including the collection optics system is provided. The collection optics system is configured to selectively collect a Raman signal from scattered light output from a target object, the collection optics system includes a non-imaging collection unit configured to collect the Raman signal and output the Raman signal, the non-imaging collection unit including an entrance surface on which the scattered light is incident and an exit surface through which the Raman signal is output, and a Raman filter provided on a portion of the entrance surface of the non-imaging collection unit and configured to block the scattered light including a fluorescence signal. Therefore, the collection optics system may suppress reception of the fluorescence signal of the scattered light and selectively collect the Raman signal.
