- esis.optics.poletto.diffraction_angle_from_grating_equation(incidence_angle, wavelength, diffraction_order, groove_density)#
Equation 13 of Poletto and Thomas rearranged to solve for diffraction angle. :param incidence_angle: Signed angle between the surface normal and the incident ray :param wavelength: Wavelength of the incident light rays :param diffraction_order: Quantum number of diffracted ray. :param groove_density: Number of grooves per unit length on the grating surface. :return: Signed angle of the diffracted light
