A system is disclosed that includes a combustor having an end cover and at least one fuel nozzle assembly extending from an inner face of the end cover. A cartridge may extend through the end cover and into the fuel nozzle assembly. The cartridge may define an opening for receiving light emitted from within the combustor. Additionally, a fiber optic cable may be disposed within the cartridge and may be configured to capture at least a portion of the light received through the opening.

1. A system, comprising: a combustor including an end cover and at least one fuel nozzle assembly extending from a first end disposed at an inner face of said end cover to a second end defining a nozzle tip, said end cover extending radially and circumferentially around an opening defined within an outer casing surrounding said combustor, said at least one fuel nozzle assembly extending along a central axis from said first end to said second end, said at least one fuel nozzle assembly defining a central passage extending along said central axis, said at least one fuel nozzle includes a plurality of concentrically arranged passages surrounding said central passage;a cartridge extending through said end cover and into said central passage of said at least one fuel nozzle assembly such that said cartridge extends longitudinally within said central passage along said central axis, said cartridge defining an opening for receiving light emitted from within said combustor assembly, wherein said cartridge is breech loaded into said central passage of said at least one fuel nozzle assembly through an opening in said end cover and is removable from said central passage of said at least one fuel nozzle assembly; anda fiber optic cable disposed within said cartridge, said fiber optic cable being configured to capture at least a portion of the light received through said opening. 2. The system of claim 1, wherein a portion of said cartridge is configured to engage an outer face of said end cover. 3. The system of claim 2, wherein said cartridge defines a flange, said flange being attached to said outer face. 4. The system of claim 1, wherein said cartridge extends within said central passage so as to be coaxially aligned with said central axis. 5. The system of claim 1, further comprising a lens mounted within said cartridge, said lens configured to focus at least a portion of the light received through said opening onto an end face of said fiber optic cable. 6. The system of claim 1, further comprising a light detector coupled to said fiber optic cable, said light detector being configured to measure a characteristic of the light transmitted through said fiber optic cable. 7. The system of claim 6, further comprising a controller communicatively coupled to said light detector, said controller being configured to analyze an output of said light detector to determine an operating condition of said combustor. 8. The system of claim 7, wherein said operating condition comprises at least one of a flame temperature and a lean blow-out precursor. 9. The system of claim 7, wherein said controller is further configured to adjust an operating parameter of said combustor based on said operating condition. 10. The system of claim 1, wherein a fluid is supplied through at least a portion of said cartridge, said fluid being directed through at least one of an inner channel and an outer channel of said cartridge. 11. The system of claim 10, further comprising a plurality of fluid outlets defined in said cartridge, said fluid being expelled from said cartridge through said plurality of fluid outlets. 12. A method, comprising: inserting a cartridge through an end cover of a combustor and into a central passage defined within a fuel nozzle assembly of said combustor, said cartridge including a cylindrical tube sized to insert and remove from said central passage through an opening in said end cover, said fuel nozzle assembly extending from a first end disposed at an inner face of said end cover to a second end defining a nozzle tip, said fuel nozzle assembly extending along a central axis from said first end to said second end, said fuel nozzle includes a plurality of concentrically arranged passages surrounding said central passage, said central passage being defined within said fuel nozzle assembly along said central axis such that, when the cartridge is inserted into said central passage, said cartridge extends longitudinally along said central axis; andcapturing light emitted from said combustor with a fiber optic cable disposed within said cartridge. 13. The method of claim 12, further comprising attaching said cartridge to said end cover. 14. The method of claim 12, further comprising measuring a characteristic of the light captured by said fiber optic cable. 15. The method of claim 14, further comprising analyzing the characteristic in order to determine an operating condition of said combustor. 16. The method of claim 15, wherein said operating condition comprises at least one of a flame temperature and a lean blowout precursor. 17. The method of claim 15, further comprising controlling an operating parameter affecting combustion within said combustor based on said operating condition. 18. The method of claim 17, wherein said operating parameter comprises at least one of fuel flow rate to said combustor and a fuel split to said fuel nozzle assembly. 19. The system of claim 11, further comprising at least one lens cooling passage in flow communication with at least one of the plurality of fluid outlets such that at least a portion of the fluid is directed through the at least one lens cooling passage in a direction of a lens mounted within said cartridge. 20. The method of claim 12, further comprising directing a fluid through said cartridge to cool at least one of said cartridge, said fiber optic cable or a lens mounted within said cartridge.
