En revanche, si toutes les longueurs d&#8217;onde visibles sont transmises (c&#8217;est-\u00e0-dire qu&#8217;elles n&#8217;absorbent rien), l&#8217;\u00e9chantillon de solution appara\u00eet blanc. Si un \u00e9chantillon de solution absorbe la lumi\u00e8re rouge (~700 nm), il appara\u00eet vert car le vert est la couleur compl\u00e9mentaire du rouge. Dans la pratique, les spectrophotom\u00e8tres visibles utilisent des LED et des filtres passe-bande optiques pour r\u00e9duire une certaine gamme de longueurs d&#8217;onde (pour filtrer les autres longueurs d&#8217;onde) afin qu&#8217;une longueur d&#8217;onde particuli\u00e8re de la lumi\u00e8re traverse un \u00e9chantillon de solution.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5ce2127 elementor-widget elementor-widget-heading\" data-id=\"5ce2127\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Colorim\u00e9trie : r\u00e9flectance de la couleur \u00e0 une longueur d'onde sp\u00e9cifique  <\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-34c4ef5 elementor-widget elementor-widget-text-editor\" data-id=\"34c4ef5\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>SCHMIDT + HAENSCH propose le r\u00e9flectom\u00e8tre <a href=\"https:\/\/amazing-pasteur.212-53-165-88.plesk.page\/fr\/produit\/saccharoflex-2020-sucre-colorimetre\/\">Saccharoflex\u00ae<\/a> qui est particuli\u00e8rement utilis\u00e9 dans l&#8217;industrie du sucre.

La couleur du cristal de sucre est un facteur important dans la norme requise pour le sucre dans toute l&#8217;UE.
