This grating calculator is intended for reference and educational purposes only. It uses Koglenik’s equations and therefore, doesn’t account for losses in multiple orders nor Fresnel reflections.
Enter the desired values in the white boxes. The Calculations box will calculate the angle of incidence and the angle of diffraction for the desired wavelength. It will also calculate the minimum thickness of the grating medium to minimize losses in multiple orders.
The “Index Modulation” graph shows what the efficiency of the grating will be for S and P polarized light at various index modulations. The resulting graph shows the potential performance of the grating.
Once you have a better idea of the parameters you would like, our grating experts can optimize the design!
