• Wood's anomalies and spectral uniformity of focusing diffractive optical elements 

      Angelskår, Hallvard; Johansen, Ib-Rune; Lacolle, Matthieu Jean P; Sudbø, Aasmund Sveinung (Journal article, 2010)
      We report on simulations and measurements of focusing diffractive optical elements, fabricated as two-level binary optics. The diffractive optical elements are designed to separate and focus four specific wavelengths in ...
