The epi-MCAM contains 24 tightly packed and synchronized epi-illumination microscope units, arranged in a 4\u2009\u00d7\u20096 planar array at 18\u00a0mm spacing. Each unit contains a unique CMOS image sensor (13 megapixels each), an objective and tube lens pair, and a beamsplitter and epi-illumination light path. An epi-MCAM capture cycle produces a stitched image covering 72\u2009\u00d7\u2009108\u00a0mm\n                    <jats:sup>2<\/jats:sup>\n                    at a micrometer scale resolution down to 2.46\u00a0\n                    <jats:italic>\u03bc<\/jats:italic>\n                    m. To image samples exceeding this native field of view, we translate the entire array across the sample surface to enable high-resolution coverage of large objects. We demonstrate the system\u2019s ability to image both flat and three-dimensionally structured reflective samples, such as semiconductor wafers and printed circuit boards, which highlight the epi-MCAM\u2019s strong potential within industrial inspection applications.\n                  <\/jats:p>","DOI":"10.1364\/oe.582497","type":"journal-article","created":{"date-parts":[[2026,3,2]],"date-time":"2026-03-02T07:00:08Z","timestamp":1772434808000},"page":"9739","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Wide-field reflective imaging with an epi-illumination multi-camera array microscope"],"prefix":"10.1364","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-5930-2103","authenticated-orcid":true,"given":"Xiangjiang","family":"Bao","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00py81415","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Ramona Optics Inc."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7749-0015","authenticated-orcid":true,"given":"Lucas","family":"Kreiss","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00py81415","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8832-5149","authenticated-orcid":true,"given":"Clare B.","family":"Cook","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00py81415","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haoyu","family":"Gong","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00py81415","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4657-4603","authenticated-orcid":true,"given":"Mark","family":"Harfouche","sequence":"additional","affiliation":[{"name":"Ramona Optics Inc."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roarke","family":"Horstmeyer","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00py81415","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Ramona Optics Inc."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,3,11]]},"reference":[{"key":"oe-34-6-9739-R1","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1016\/j.compind.2014.10.006","type":"journal-article","volume":"66","author":"Huang","year":"2015","journal-title":"Comput.
