Abstract
There is provided a Raman signal detection including a laser emitter and an optical element. The optical element includes an optical element body, an emitter face with a short pass optical coating, a Raman signal face with a long pass optical coating and a sample face. The optical element is positioned with a laser emitter output beam incident upon the emitter face. The emitter face receives the laser emitter output beam and transmits an emitter face output beam through the optical element body and the sample face to emit a sample face output beam. The sample face receives and transmits a sample reflection beam generated from the sample face output beam to the emitter face. The emitter face reflects and transmits the sample reflection beam the sample reflection beam through the Raman signal face to emit a Raman signal output beam to a Raman signal detector.
