SNR of every single point of your scan is hard to calculate. It depends on electronic, source stability, detector noises, integration time etc. etc. SNR will also change with wavelength. Fortunately, with 420 scans you can calculate 420 standard deviations and then use it to calculate your SNR :)

Ramadan Hasan

Thanks Rafal

I have 1000 scans for 256 different wavelengths, the Sd is calculated. But I do not know what the best SNR ?
