Spectrometric assembly and method for determining a temperature value for a detector of a spectrometer

An assembly, comprising:

• a mechanism configured to spectrally split incident light;
• a first optical detector configured to provide spectrally resolved detection of a spectral region of the split light;
• and
• a second optical detector configured to detect a portion of the spectral region to be detected by the second optical detector,
• wherein a sensitivity of the second detector to temperature is significantly less than a sensitivity of the first optical detector to temperature.

A method for determining a temperature value of a first optical detector for spectrally resolved detection of a spectral region of incident light, the method comprising:

• determining, via the first optical detector, a detection signal for a portion of the spectral region;
• determining, via a second optical detector, a reference signal for the portion of the spectral region;
• and
• determining, based on the detection signal and the reference signal, a relative temperature value for the first optical detector,
• wherein a sensitivity of the second detector to temperature is significantly less than a sensitivity of the first optical detector to temperature.

A computer program product tangibly embodied in a computer readable medium comprising instructions to cause a computer to:

• determine a temperature value of a first optical detector for spectrally resolved detection of a spectral region of incident light by:
• determining, via the first optical detector, a detection signal for a portion of the spectral region;
• determining, via a second optical detector, a reference signal for the portion of the spectral region;
• and
• determining, based on the detection signal and the reference signal, a relative temperature value for the first optical detector,
• wherein a sensitivity of the second detector to temperature is significantly less than a sensitivity of the first optical detector to temperature.
