The system has been tested for reflectance and luminescence measurements, but can also be customized for transmittance measurements. This study includes the performance results of the developed system, as well as examples of spectral images. Discussion of the system relates it to existing systems and methods. The wide range spectral imaging system that has been developed is however highly customizable and has great potential in many practical applications.<\/jats:p>","DOI":"10.3390\/s131114500","type":"journal-article","created":{"date-parts":[[2013,10,28]],"date-time":"2013-10-28T09:07:13Z","timestamp":1382951233000},"page":"14500-14510","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["A Wide Spectral Range Reflectance and Luminescence Imaging System"],"prefix":"10.3390","volume":"13","author":[{"given":"Tapani","family":"Hirvonen","sequence":"first","affiliation":[{"name":"Institute of Photonics, University of Eastern Finland, P.O.Box 111, FI\u201380101 Joensuu, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Niko","family":"Penttinen","sequence":"additional","affiliation":[{"name":"Institute of Photonics, University of Eastern Finland, P.O.Box 111, FI\u201380101 Joensuu, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Markku","family":"Hauta\u2013Kasari","sequence":"additional","affiliation":[{"name":"Institute of Photonics, University of Eastern Finland, P.O.Box 111, FI\u201380101 Joensuu, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mika","family":"Sorjonen","sequence":"additional","affiliation":[{"name":"Palom\u00e4entie 4, FI\u201388620 Korholanm\u00e4ki, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kai\u2013Erik","family":"Peiponen","sequence":"additional","affiliation":[{"name":"Institute of Photonics, University of Eastern Finland, P.O.Box 111, FI\u201380101 Joensuu, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2013,10,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"92","DOI":"10.1366\/000370210790572016","article-title":"Feasibility of near-infrared spectroscopy for on-line grading of sawn lumber","volume":"64","author":"Fujimoto","year":"2010","journal-title":"Appl.
