Study on Some Characteristics of Planar Holographic Sinusoidal Gratings and Blazed Gratings Used in UV Region in Theory
Diffraction efficiency of Al-coated triangle and holographic sinusoidal grating used in UV region are calculated using the differential formalism of exact electromagnetic theory.The efficiency curves of blazed characteristic of sinusoidal grating is presented.And the influence of apex angle on diffraction efficiency of triangle grating is debated.
