Optical‐transform methods remain useful aids in determining the structures of polymers, and other disordered materials, from X‐ray scattering data. Hitherto a major difficulty has been the preparation of diffracting screens which contain sufficient information to specify adequately the material being studied. The Optronics P‐1500 Photowrite system overcomes this difficulty. The equipment is described briefly and two examples of its use in optical transform methods are given.
