The combustor (40) forms a combustion chamber (98). The monochromator (128) is disposed outside the combustion chamber (98). The monochromator (128) is configured to receive an optical input (130) from the combustion chamber (98) and direct an optical output (132). The optical input (130) has a range of light wavelengths. The optical output (132) has a subset of the range of light wavelengths. The photodetector assembly (122) is disposed outside the combustion chamber (98). The photodetector assembly (122) is configured to receive the optical output (132) from the monochromator (128) and generate an output signal representative of one or more optical characteristics of the optical output (132).",
