Abstract
A Raman optical method and apparatus is utilized to automatically and accurately recognize laser power measurements made at a desired illumination sample plane. From such a configuration, the methods and systems disclosed herein, enable the support of multiple optical wavelengths coupled with essential components, such as, but not limited to, filters, objectives, reflectors, etc., to provide the capability of displaying and controlling the optical power at the desired sample plane through storage of power calibration factors that are associated with such components. In particular, the system utilized herein, can recognize the installation of components and recalls stored calibration factors that are associated with such components to ensure an accurate power measurement at the illuminated sample plane.
