View Resource Double Exposure Makes Dense High-Resolution Diffractive Optics

This article from SPIE discusses an electron-beam-lithography technique which fabricates diffractive optical structures such as classic Fresnel-zone-plate lenses with fine features. Diffractive optical elements are especially useful in parts of the electromagnetic spectrum, such as the soft x-ray region, where suitable materials for reflective and refractive structures are not available.
