Gold-plated external reflective mirror is an optical element designed as an external reflective structure, with a layer of gold film coated on the outer surface of the reflector. It is generally based on optical glass or other transparent materials, with a layer of gold film coated on the surface to achieve a specific optical effect. A protective layer (such as silicon dioxide) can also be coated on the outer layer of the gold film to prevent the gold film from being scratched or oxidized. Features and performance High reflectivity: The gold film has a high reflectivity in a wide wavelength range (such as 0.75-20um), usually up to 96%. This makes the gold-plated external reflector have excellent performance and good stability in occasions with high reflectivity requirements.

Gold-plated external reflective mirror is an optical element designed as an external reflective structure by coating a gold film on the outer surface of the reflector. It is generally made of optical glass or other transparent materials as a substrate, with a layer of gold film coated on the surface to achieve a specific optical effect. A protective layer (such as silicon dioxide) may also be coated on the outer layer of the gold film to prevent the gold film from being scratched or oxidized.
Features and Performance
High reflectivity: Gold film has a high reflectivity over a wide wavelength range (such as 0.75-20um), usually reaching more than 96%. This makes gold-plated external reflective mirrors perform well in applications that require high reflectivity.
Good stability: The strength and stability of gold film are better than other metals, and it can maintain long-term stable reflective performance.
Strong protection: The protective layer (such as silicon dioxide) on the outer layer can effectively prevent the gold film from being scratched or oxidized, extending the service life of the reflector.
Customization: Gold-plated external reflective mirrors can be customized according to specific needs, including size, shape, reflectivity and other parameters can be adjusted according to the application.
Product Features
High reflectivity: The reflectivity can reach 95%-99% in the infrared band (IR, usually 700 nm to 10 µm). It also has good reflective performance in the visible light band, showing a golden appearance.
Excellent thermal stability: The gold-plated layer shows extremely high tolerance to high temperature environments and is suitable for high-power laser systems.
Anti-oxidation performance: The gold layer has natural anti-oxidation properties and is not easily affected by moisture or chemical corrosion. Optional protective dielectric films (such as silicon dioxide) can further enhance durability.
Low scattering and absorption: The gold-plated surface is smooth and has high reflection efficiency, which is suitable for precision optical applications.
External reflection design: Optimizes external light reflection and reduces stray light and energy loss inside the system.
Optional configuration
Substrate material: Optical glass, silicon, germanium, sapphire, etc., adapted to different bands and environments.
Protective coating: Anti-reflective coating or wear-resistant coating can be added to extend service life.
Size and shape: Support customized diameter, thickness and geometry.
Application areas
Infrared optical systems: used in infrared spectrometers, thermal imagers, and remote sensing equipment.
High-power laser systems: laser reflector components that perform well in high-power infrared lasers (such as CO₂ lasers).
Astronomy and aerospace: used in astronomical telescopes and satellite sensors to ensure efficient transmission and reflection of infrared light.
Medical equipment: key components in infrared laser therapy devices and diagnostic systems.
Scientific research and industrial equipment: widely used in spectral analysis, precision measurement, and industrial processing.
