Paper Abstract

Two different approaches to the production of computer generated diffractive optical elements have been studied. Computer generated diffractive optical elements have been written in binary form in chrome on glass using the electron beam facilities at the Rutherford Appleton Laboratory in the UK. These elements have been used as masters for subsequent copying into DCG to obtain higher diffraction efficiencies. Intermediate diffraction efficiency has been obtained by simple contact printing into photoresist. An alternative approach has been to write the elements directly into photoresist with careful control of the profile or blaze of each ruling. Using both these techniques conventional and novel elements have been produced and evaluated.
