Patent ID: 7564549

Claim:
A system for performing metrology of a sample of fullerenes, the system comprising: an illumination source that produces a first energy beam; a monochromator that receives the first energy beam and that selects a band of wavelengths of the first energy beam to transmit to the sample; a pyroelectric detector upon which the sample is attached and that produces a first output signal in response to the first energy beam; a laser arranged to provide a second energy beam to the sample, wherein the monochromator receives a third energy beam emitted from the sample in response to the second energy beam and selects a band of wavelengths of the third energy beam; a Raman detector that receives the third energy beam and produces a second output signal in response to the third energy beam; a light-tight enclosure that encloses the illumination source, monochromator, and laser, wherein the light-tight enclosure has a slit for transmitting an energy beam to the sample, wherein the light-tight enclosure also encloses the Raman detector, and wherein the laser and the Raman detector are in different portions of the light-tight enclosure.
