Thin membranes matter for solar science, he said, because these sieves transmit up to seven times more light than thicker materials. Denis\u2019s work will open new ways to study the Sun in better detail and understand its influence on Earth and the solar system.<\/p>\n\n\n\n<p>Working closely with solar scientists over many years through Goddard \u2019s <a href=\"https:\/\/www.nasa.gov\/goddard\/technology\/\" target=\"_blank\" rel=\"noreferrer noopener\">IRAD, or Internal Research and Development<\/a> program, Denis developed new ways to create wider and thinner membranes of silicon and niobium. These photon sieves, created in Goddard\u2019s Detector Development Laboratory, are so thin they must be supported by a honeycomb lattice of thicker silicon to prevent tearing. Etched with microscopic holes in a circular pattern, they refract light similar to Fresnel lenses used in lighthouses. Extreme ultraviolet light passing through this sieve is bent gradually inward to a distant receiver.<\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-cover \"><a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/11\/dennis231114-00003-copy.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"2048\" height=\"1568\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/11\/dennis231114-00003-copy.jpg?w=2048\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"an 8-inch wafer of silicon, with hair-thin panels etched with microscopic holes.\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/11\/dennis231114-00003-copy.jpg 6603w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/11\/dennis231114-00003-copy.jpg?resize=300,230 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/11\/dennis231114-00003-copy.jpg?resize=768,588 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/11\/dennis231114-00003-copy.jpg?resize=1024,784 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/11\/dennis231114-00003-copy.jpg?resize=1536,1176 1536w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/11\/dennis231114-00003-copy.jpg?resize=2048,1568 2048w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/11\/dennis231114-00003-copy.jpg?resize=400,306 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/11\/dennis231114-00003-copy.jpg?resize=600,459 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/11\/dennis231114-00003-copy.jpg?resize=900,689 900w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/11\/dennis231114-00003-copy.jpg?resize=1200,919 1200w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/11\/dennis231114-00003-copy.jpg?resize=2000,1531 2000w\" sizes=\"(max-width: 2048px) 100vw, 2048px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">Photon sieves like  this are cut from a single wafer of silicon or niobium to focus extreme ultraviolet light – a difficult wavelength to capture.<\/div><div class=\"hds-credits\">NASA \/ Christopher Gunn<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>\u201cIt\u2019s a sheer physical challenge to construct sieves with such precision,\u201d said Goddard heliophysicist Dr. Doug Rabin. \u201cTheir smallest features are a few microns across.
