The Compovision imaging system utilizes a near-infrared camera1 developed upon Sumitomo Electric's compound semiconductor and optical communications technologies. Since its launch in August 2010, the Company has been exploring its use in a wide range of applications including quality control of food products and inspections in the blister packing process2 for inclusion of incorrect tablets.
In April 2012, Sumitomo Electric and Professor Yukihiro Ozaki at Kwansei Gakuin University began a joint research program on a tablet coating inspection technology for use on production lines, on the crystallinity inspection of polylactic acid—a polymeric organic material3,and on polymer blending ratio inspection. These technologies combine the university's analysis technology and spectra4 acquired with the near-infrared camera used in Compovision.
Tablet coating inspection has been conventionally difficult in production processes. However, the newly developed inspection technology has enabled fast, on-the-spot inspection for tablets with coating failure and different tablets accidentally contained, thus eliminating the need to dispose of intended tablets packed with rejected tablets.
Consequently, this new technology is expected to improve production efficiency and reduce costs. With the capability of total inspection, it will also help improve product safety.
In polymeric material inspection, we have successfully measured an important property, the crystallinity, of polylactic acid5—a focus of attention as a bioplastic—and blending ratios of blended polymers.
Following the test measurement, Professor Yukihiro Ozaki said: “Compovision is an all-new imaging system incorporating a near-infrared camera that Sumitomo Electric has developed by drawing on its comprehensive expertise in various technical fields. No near-infrared cameras would compete with this camera in terms of the processing speed and the range of wavelengths. With great user friendliness, Compovision will find wide applications including the analysis of polymers and tablets as well as that of organic materials and food products.”
The research results will be presented by Dr. Daitaro Ishikawa of Kwansei Gakuin University at the international symposia FACSS-SCIX 2012 held from September 30 to October 5 in Kansas City, Missouri, United States.
Additionally, Sumitomo Electric will provide a dynamic exhibition of the Compovision near-infrared camera at P-MEC (http://www.p-mec.com/), part of the global portfolio of pharmaceutical events, CPhI, ICSE, P-MEC and InnoPack, held from October 9 to 11, 2012 in Madrid, Spain. The Company will demonstrate the inspection of tablets contained in blister packs, determination of capsule contents, and distinction of mixed powders. The research results described above will also be on display. Please drop by our booth.
