outline： The application differences between gold, silver, and aluminum-plated reflective mirrors mainly lie in their different advantages in reflection band, performance characteristics, and cost; gold-plated reflective mirrors Advantages: High infrared reflectivity (>95%), high temperature resistance, and corrosion resistance.
The main differences in the applications of gold, silver, and aluminum-coated reflecting mirrors lie in their reflection bands, performance characteristics, and cost. A brief summary is as follows:
1. Gold-coated reflecting mirrors
Advantages: High infrared reflectivity (>95%), high temperature resistance, and corrosion resistance.
Applications:
Infrared instruments (such as thermal imagers and spectrometers);
High-temperature environments (such as industrial furnaces and space equipment);
Astronomical telescopes (to reduce thermal noise).
2. Silver-coated reflecting mirrors
Advantages: High visible light reflectivity (>95%), and color-neutral imaging.
Applications:
Optical instruments (microscopes, laser resonators);
Precision imaging equipment (projectors, movie projectors);
Decorative mirrors (jewelry stores, homes).
3. Aluminum-coated reflecting mirrors
Advantages: Low cost, high ultraviolet reflectivity (>90%), and wear resistance.
Applications:
Everyday items (vanity mirrors, car rearview mirrors);
Ultraviolet equipment (UV curing machines, sensors);
Low-cost applications (educational instruments, simple optical components).
outline： The 20th "China Optics Valley" International Optoelectronics Expo (hereinafter referred to as the Optics Expo) opened on May 15, 2025, at the China Optics Valley Science and Technology Convention and Exhibition Center. The expo was hosted by the People's Government of Hubei Province and co-hosted by the People's Government of Wuhan City, the Hubei Provincial Department of Economy and Information Technology, and the Management Committee of Wuhan East Lake High-tech Development Zone. Themed "Light Connects All Things, Intelligence Leads the Future," this year's expo was included for the first time in the United Nations Educational, Scientific and Cultural Organization's (UNESCO) global series of events for the International Day of Light, making it a major focus in the global optoelectronics field.
