The heart of any spectroradiometric system is the monochromator, but…
It must give the right bandpasses – not too large and not too small
It must give high spectral purity (low stray light) so only the wavelength of interest is detected

Gratings diffract light at different angles depending on wavelength
400nm will also diffract at the same angle as 800nm (since 2 x 400 = 800)
A blocking filter removes the 400nm so just 800nm is left

In order to characterize their performance in a particular applications, single detectors, array detectors and assemblies often need spectral response to be known
For example, photopic detectors can be analysed for V() matching
