WebAstigmatism (optical systems) An optical system with astigmatism is one where rays that propagate in two perpendicular planes have different foci. If an optical system with astigmatism is used to form an image of a cross, the vertical and horizontal lines will be in sharp focus at two different distances. The term comes from the Greek α- ( a ... WebMay 5, 2024 · OpticStudio models diffractive power independent to the substrate index and the surface sag; diffractive power introduces phase change to rays. All diffractive surfaces in OpticStudio bends rays according to the following equation: Where: M is the diffraction order λ is the wavelength T is the grating period (inverse of the line spacing, d).
