QB Series Near-Infrared Cutoff Filter
The QB series near-infrared cut-off filters have strong absorption in the near-infrared, which can significantly improve imaging problems such as ghosting, stray light and color cast, and are widely used in mobile phone filters (IRCF) and low-pass filters (OLPF). Materials include QB5 series, QB6 series and QB7 series glass to meet different infrared suppression requirements. IRCF and OLPF filters of various specifications are available. The main processing sizes for OLPF are 41mm×37mm×0.8mm, 28mm×22mm×0.4mm and 16.8mm×12.7mm×0.3mm, and the main processing sizes for IRCF are 77mm×77mm×0.21mm and 55mm×42mm×0.145mm, and can be customized according to customer requirements.
