Wide Spectrum And High-Efficiency Electromagnetic Shielding Optical Window Element
Recently, the high-throughput radiation protection materials and technology research group led by Wang Pengfei, a researcher in the photonic functional materials and Devices Research Laboratory of Xi'an Institute of Optics and precision machinery, Chinese Academy of Sciences, developed a wide spectrum and efficient electromagnetic shielding optical window element. The average electromagnetic shielding efficiency of this optical window element in the range of 1-18 GHz is > 50 dB, its visible near-infrared transmittance is > 80%, and the element size can reach more than 350 mm.
Electromagnetic shielding optical window is the core functional part of various electronic instrument display screens, aircraft and vehicle windows, photoelectric detector systems, etc. to ensure the normal operation of photoelectric instruments and equipment in the microwave and electromagnetic pulse radiation environment. Compared with the optical shielding window with periodic grid, this product has higher transmittance and electromagnetic shielding efficiency, can effectively reduce the high-order diffraction of light, and can meet the requirements of high-quality optical imaging applications on the basis of wide-band strong electromagnetic shielding; The process of preparing large-size shielded light window is simpler and the manufacturing cost is relatively low.
The research work is supported by the joint independent subordinate projects of the aerospace technology department and the basic scientific research department of Xi'an Institute of Optics and mechanics. The innovative design of high conductivity optical window core matrix glass material is expected to continue to improve the comprehensive electromagnetic protection performance of electromagnetic shielding optical window elements, and The interdisciplinary innovation and sustainable development of Optoelectronics and other disciplines play an important role in promoting.
