Abstract: Raman analysis systems are partitioned to provide for cost-effective flame resistance and explosion resistance, including relatively small enclosures associated with particular subsystems. One or more of an excitation source, spectrograph and/or controller are disposed in separate, flame-resistant or explosion-resistant enclosures. A remote optical measurement probe may also be disposed in a separate flame-resistant or explosion-resistant enclosure. A grating and a detector of the spectrograph may be disposed in separate enclosures, with sealed windows therebetween to deliver a Raman spectral signal from the optical grating to the detector. The sealed window of the detector enclosure may serve the dual purpose of maintaining flame resistance or explosion resistance while maintaining cooling within the enclosure. Wireless interfaces may be used for communications between the enclosures where practical to reduce or eliminate physical electrical feedthroughs.
