Scientific paper

The first solar images using a photon sieve were obtained in H-alpha at NASA Goddard Space Flight Center. The first sieve used consists of 1500 fresnel zones comprising 15 million holes in a chrome layer on a glass substrate to yield a focal length of 400 mm at a wavelength of 656.3 nm. Results of the observations are discussed, as well as the positive implications for the use of diffractive optics on deployable membranes for extremely high resolution (0.01 arcsec) imaging from space.
