Abstract
A polarizing effect is achieved for light having wavelengths less than 250 nm by orienting an antireflector at an incidence angle between 65° and 75°. Despite limited choices for materials, the antireflector is constructed of layers that alternate in refractive index to exploit the mechanism of interference for limiting the reflectivity of one linear polarization component of the light. The same combination of layers supports the reflectivity of an orthogonal linear polarization component. The light reflected from the antireflector is highly polarized.
