Abstract:
A multilayer antireflection coating, comprising, from the medium side, multiple stacked layers of high-refractive-index material and low-refractive-index material arranged alternatingly in a sequentially stacked manner, each alternating layer of the high-refractive-index material having the same optical thickness, and each alternating layer of the low-refractive-index layer having the same optical thickness, the multilayer antireflection coating inhibiting reflection therefrom of incident p-polarized light having a wavelength .lambda. such that 150 nm.ltoreq..lambda..ltoreq.250 nm incident on the multilayer antireflection coating at an angle of incidence .theta. such that 70.degree..ltoreq..theta..ltoreq.80.degree..
