| Jul 29 at 6:39 | comment | added | user668074 | thank you for your comment. My spectrometer seems to be intended for reflective surfaces and reommends a metal surface or aluminium mirror as a reference. Regarding how it handles data, I may have to search the manuals more, so far there is not much information on the processing, mainly tutorial information and instrutions. | |

If the reference material is the aluminum mirror, that will give you the baseline R100 (100% reflectance) which would be then the reference (if you get e.g. power values instead of R values). It would really depend on how your spectro handles data | |

Is that suitable to use if my samples are polished and do not have significant diffuse reflections? My samples are mirror like. Regarding a calibration run, my instrument takes a baseline measurement of a reference material (in my case, it is an aluminium mirror). | |
