class=\"ai-optimize-9\"><strong>Reflectometric measurement using a integrating sphere<\/strong><\/p>\r\n<p class=\"ai-optimize-10\">The AL-01 measures <strong>solar reflectance <\/strong>using a <strong>integrating sphere<\/strong>, employing a reflectometric approach suited to the characterisation of building materials and urban surfaces.<\/p>\r\n<p class=\"ai-optimize-11\">This technology enables:<\/p>\r\n\r\n<ul>\r\n \t<li class=\"ai-optimize-12\"><strong>robust and reproducible measurements<\/strong><\/li>\r\n \t<li class=\"ai-optimize-13\">accurate accounting for <strong>diffuse reflections<\/strong><\/li>\r\n \t<li class=\"ai-optimize-14\">suitable for use on <strong>rough, heterogeneous or textured <\/strong>surfaces<\/li>\r\n \t<li class=\"ai-optimize-15\">consistency
