% Descr:    Example code to calculate pixel:wavelength mapping when pixel#
%           for 436nm and 546nm peaks are known
%
% Concept:
% With an incidence angle to the grating of 45-deg, and the camera image
% plane thus parallel to the grating, the 524nm diffraction angle will be
% 0-deg; relative to the camera normal (perpendicular to the image plane
