摘要
An optical element includes a transparent substrate having a planar front surface, and a multilayer structure, which is formed on the front surface of the substrate and includes multiple thin film layers, including an outer layer that is exposed to ambient air. The multilayer structure defines, at a target wavelength, a series of resonant cavities that create, for a beam of light at the target wavelength that is incident on the optical element at a target angle, a passband for an s-polarization component of the beam and a stopband for a p-polarization component of the beam.
