Abstract
An apparatus for generating a Raman signal of a test sample is disclosed. The apparatus includes a first optical path, a second optical path, a first station, and a second station. The first optical path is adapted for coupling with a radiation source that produces a test beam at the first optical path. The first station is responsive to the test beam and is adapted to house a test standard. The second station is responsive to the test beam and is adapted to house the test sample. In response to the test beam, Raman radiation from the test standard and the test sample are combined and directed to the second optical path, which is adapted for coupling with a spectrometer and a detector for producing a Raman spectrum of the test sample.
