Patent ID: 8111392

Claim:
A Raman spectrometer system for automatically displaying and substantially controlling a desired power at a sample plane, comprising: one or more secured optical components and one or more inter-changeable optical components configured along an optical path of said Raman spectrometer system; one or more nonvolatile memory devices coupled with one or more of said secured and one or more of said inter-changeable optical components, wherein said one or more nonvolatile memory devices coupled with said one or more of secured and one or more of said inter-changeable optical components further comprise a data set of respective optical characteristics of an individual or a group of said one or more secured and said one or more inter-changeable optical components; computer means configured to download said data set of respective optical characteristics; and a detector configured to monitor in-situ an optical power input into the optical path of said Raman spectrometer system, wherein said computer means while in feedback communication with said detector adjusts the input optical power based on said data set of respective optical characteristics so that the accurate optical power at a desired sample plane is displayed and automatically controlled for said spectrometer system.
