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:
- one or more light sources configured to be deactivated during a dark state;
- a spectrometer configured to determine a dark-state baseline calibration value during the dark state;
- and
- a diffuser configured to diffuse light,
- the spectrometer being further configured to perform a measurement based on the light and based on the dark-state baseline calibration value.
