I am using Avantes spectrometer. A set of six spectrometers covering wavelength range from 220 to 960 nm.

I need a response curve for the spectrometer equipped with two spectrometers 2400 lines/mm grating (220-440 nm) and CMOS 4096 pixel detector and three spectrometers with 1800 lines/mm grating (440-800 nm).
