Here, \u00a0the solid immersion grating microspectrometer (SIG\u2010\u00b5SPEC) for high spectral resolution in a broad operational wavelength range is reported. The spectroscopic module incorporates a silicon microslit, index\u2010matched lens, plane mirrors, solid immersion grating (SIG), and a CMOS line sensor within a small form factor. The SIG facilitates high angular dispersion of light on a planar focal plane, resulting in an average spectral resolution of 5.8\u00a0nm, with over 76% maximum sensitivity from 400 to 800\u00a0nm. SIG\u2010\u00b5SPEC measures the spectral reflectance of fruits at different ripening stages, clearly revealing changes in the chlorophyll absorption band. The measured spectrum is further utilized for the precise prediction of the soluble solid content (SSC) levels, achieving a high correlation (R\n                    <jats:sup>2<\/jats:sup>\n                    = 0.91) and a ratio of prediction\u2010to\u2010deviation of 2.36. This compact microspectrometer holds the potential for precise and non\u2010invasive spectral analysis across point\u2010of\u2010care fields.\n                  <\/jats:p>","DOI":"10.1002\/advs.202304320","type":"journal-article","created":{"date-parts":[[2023,10,18]],"date-time":"2023-10-18T01:08:50Z","timestamp":1697591330000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Fully Integrated Ultrathin Solid Immersion Grating Microspectrometer for Handheld Visible and Near\u2010Infrared Spectroscopic Applications"],"prefix":"10.1002","volume":"10","author":[{"given":"Jung\u2010Woo","family":"Park","sequence":"first","affiliation":[{"name":"Department of Bio and Brain Engineering Korea Advanced Institute of Science and Technology (KAIST)  291 Daehak\u2010ro Yuseong\u2010gu Daejeon 34141 Republic of Korea"},{"name":"KAIST Institute for Health Science and Technology (KIHST) Korea Advanced Institute of Science and Technology (KAIST)  291 Daehak\u2010ro Yuseong\u2010gu Daejeon 34141 Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaehun","family":"Jeon","sequence":"additional","affiliation":[{"name":"Department of Bio and Brain Engineering Korea Advanced Institute of Science and Technology (KAIST)  291 Daehak\u2010ro Yuseong\u2010gu Daejeon 34141 Republic of Korea"},{"name":"KAIST Institute for Health Science and Technology (KIHST) Korea Advanced Institute of Science and Technology (KAIST)  291 Daehak\u2010ro Yuseong\u2010gu Daejeon 34141 Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gi Beom","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Bio and Brain Engineering Korea Advanced Institute of Science and Technology (KAIST)  291 Daehak\u2010ro Yuseong\u2010gu Daejeon 34141 Republic of Korea"},{"name":"KAIST Institute for Health Science and Technology (KIHST) Korea Advanced Institute of Science and Technology (KAIST)  291 Daehak\u2010ro Yuseong\u2010gu Daejeon 34141 Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4799-7816","authenticated-orcid":false,"given":"Ki\u2010Hun","family":"Jeong","sequence":"additional","affiliation":[{"name":"Department of Bio and Brain Engineering Korea Advanced Institute of Science and Technology (KAIST)  291 Daehak\u2010ro Yuseong\u2010gu Daejeon 34141 Republic of Korea"},{"name":"KAIST Institute for Health Science and Technology (KIHST) Korea Advanced Institute of Science and Technology (KAIST)  291 Daehak\u2010ro Yuseong\u2010gu Daejeon 34141 Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,10,17]]},"reference":[{"key":"e_1_2_8_1_1","doi-asserted-by":"publisher","DOI":"10.1038\/nphoton.2009.185"},{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41377-022-00853-1"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tifs.2019.01.015"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/lsa.2017.26"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.talanta.2020.121809"},{"key":"e_1_2_8_6_1","first-page":"772","volume":"24","author":"Armenta S.","year":"2005","journal-title":"Anal.
