A hemispherical lens is added between the entrance slit and collimating mirror, which can correct astigmatism and increase numerical aperture at the same time.

The comparison of the improved Czerny\u2013Turner spectrometer with the conventional Czerny\u2013Turner spectrometer is also thoroughly described in the paper. The ray-tracing results show that the RMS spot radius of the improved Czerny\u2013Turner spectrometer decreases from over 200\u00a0\u00b5m to less than 18\u00a0\u00b5m compared with the traditional Czerny\u2013Turner spectrometer.\n                  <\/jats:p>","DOI":"10.1364\/ao.453036","type":"journal-article","created":{"date-parts":[[2022,3,18]],"date-time":"2022-03-18T09:00:10Z","timestamp":1647594010000},"page":"3077","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Advanced optical design of Czerny\u2013Turner spectrometer with high flux and low aberration in broadband"],"prefix":"10.1364","volume":"61","author":[{"given":"Su","family":"Wu","sequence":"first","affiliation":[{"name":"Anhui Institute of Optics and Fine Mechanics, Chinese Academy of Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tao","family":"Wang","sequence":"additional","affiliation":[{"name":"Anhui Institute of Optics and Fine Mechanics, Chinese Academy of Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chan","family":"Huang","sequence":"additional","affiliation":[{"name":"Hefei University of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiapeng","family":"Gu","sequence":"additional","affiliation":[{"name":"Anhui Institute of Optics and Fine Mechanics, Chinese Academy of Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Yu","sequence":"additional","affiliation":[{"name":"Anhui Institute of Optics and Fine Mechanics, Chinese Academy of Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui","family":"Xue","sequence":"additional","affiliation":[{"name":"Anhui Institute of Optics and Fine Mechanics, Chinese Academy of Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuan","family":"Shen","sequence":"additional","affiliation":[{"name":"Hefei Normal University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2022,4,4]]},"reference":[{"key":"ao-61-11-3077-R1","doi-asserted-by":"crossref","first-page":"W3","DOI":"10.1364\/PIBM.2017.W3A.112","article-title":"A Czerny-Turner spectrometer for ultrahigh resolution SD-OCT","volume-title":"International Conference on Photonics and Imaging in Biology and Medicine","author":"Peng","year":"2017"},{"key":"ao-61-11-3077-R2","doi-asserted-by":"publisher","first-page":"599610","DOI":"10.1117\/12.630143","volume":"5996","author":"Grueger","year":"2005","journal-title":"Proc.
