With the rapid development of various scientific and technological fields at home and abroad, the manufacturing technology and performance of optical fiber imaging materials have been continuously improved. Optical night vision and particle detection have been extended to high-energy ray detection, medical equipment and many scientific research fields. The terminology, technical requirements and test methods for thermal and chemical performance indicators can no longer meet the actual performance level and requirements of this type of product. Therefore, it is necessary to revise the existing national standards for optical fiber image transmission components in my country and introduce new terms, technical requirements and The test method is conducive to promoting the innovation and development of optical fiber imaging element technology. In view of the above reasons, in order to standardize the scientificity and advancement of the standards in the production of optical fiber image transmission components, build a For quality and technical exchanges between users, it is necessary to revise the relevant contents of GB/T 20244-2006.
