spectrum of a sample accurately, spectral analysis of the data must take into
account the spectrum of the light source.
In a monochromator, wavelengths are sampled sequentially. If a diffraction
grating is used as the dispersing mechanism, the broadband light emitting
from the illumination source strikes the grating at an angle of incidence and
is diffracted at an angle of diffraction. The angle of diffraction varies with
wavelength, and hence manipulating the angle of light incidence can vary
the wavelength of light emitted from the monochromator. The theory behind
dispersion mechanisms, specifically diffraction gratings and prisms, is well cov-
ered in the literature [10]. Some key characteristics of a spectroscope are (1) its
spectral resolution, ...
