Collection optics system for spectrometer and Raman spectral system
First Claim
1. A collection optics system for a spectrometer, the collection optics system being configured to selectively collect a Raman signal from scattered light output from a target object, the collection optics system comprising:
- a non-imaging collection unit configured to collect the Raman signal from the scattered light and output the Raman signal, the non-imaging collection unit comprising an entrance surface on which the scattered light is incident and an exit surface through which the Raman signal is output, the entrance surface being configured to he brought in contact with the target object; and
a Raman filter provided on a portion of the entrance surface of the non-imaging collection unit and configured to block a portion of the scattered light comprising a fluorescence signal.

Abstract
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.
