Abstract
A device may determine a calibration value for a spectrometer using light from a first light source; deactivate the first light source after determining the calibration value; perform measurement with regard to a sample based on the calibration value, wherein the measurement of the sample is performed using light from a second light source; determine that the calibration value is to be updated; and update the calibration value using the light from the first light source.
Claims20
A system comprising:
- a spectrometer light source to generate light used for determination of a baseline calibration value;
- and
- a sensor to:
- receive the light used for determination of the baseline calibration value,
- receive light transmitted via a sample, and
- perform spectroscopy with regard to the sample based on the light transmitted via the sample and the baseline calibration value.
3 more elements
A method, comprising:
- receiving, by a sensor of a spectrometer system and from a spectrometer light source of the spectrometer system, light used for determination of a baseline calibration value;
- determining, by the spectrometer system, the baseline calibration value based on the light used for determination of the baseline calibration value;
- receiving, by the sensor of the spectrometer system, light transmitted via a sample;
- and
- performing, by the spectrometer system, spectroscopy with regard to the sample based on the light transmitted via the sample and the baseline calibration value.
2 more elements
A system, comprising:
- process windows that partially or completely enclose a sample;
- a first light source to generate first light;
- a second light source to generate second light;
- and
- one or more components to:
- receive the first light;
- determine a baseline calibration value based on the first light;
- receive the second light after the second light is transmitted via the sample;
- and
- perform spectroscopy with regard to the sample based on the second light and the baseline calibration value.
