Spectrometer Noise

To measure the dark current, we take one spectra and analyze as a function of exposure time:

Mean:

Std:

Wavelength dependent:

 

We take two spectra and subtract the two. Below is a plot of the residual as a function of exposure time:

 

Mean residual:

Std residual:

Wavelength dependent residual:
