Zusammenfassung:Not Applicable This invention relates to an accessory for incorporation into Raman and other spectroscopic instruments for combining shuttering and spectroscopic calibration functions. The accessory is comprised of an assembly with at least two positions that may be inserted into the light path, one position allowing light to be directed to and from the sample, and another position containing a reference standard that blocks the beam and provides a shuttering function. When the light strikes the reference standard, a reference spectrum is produced that may be used to calibrate the spectrograph. The device is especially useful in combination with compact sampling accessories for Raman spectroscopy.
