Protected Gold Mirrors are premium optical components designed to provide superior reflectivity across the infrared spectrum. These mirrors feature a highly reflective gold coating, protected by a durable dielectric layer, ensuring longevity and excellent performance in challenging environments. Protected gold mirrors are particularly suited for applications requiring high reflectance in the infrared (IR) range, such as thermal imaging, spectroscopy, and laser systems.

Key Features:

1. Exceptional Reflectivity:

   • Reflectance (Ravg > 98% @ 2,000 – 12,000 nm): The protected gold coating offers outstanding reflectivity in the near-infrared (NIR), mid-wave infrared (MWIR), and long-wave infrared (LWIR) spectral regions, making it an ideal choice for IR-sensitive applications.

2. Protective Coating:

   • Durable Dielectric Layer: The gold coating is safeguarded by a dielectric layer, providing protection against environmental factors such as oxidation, abrasion, and contamination. This ensures long-term stability and durability, even in harsh or outdoor conditions.

3. Infrared Optimization:

   • Optimal for IR Applications: Gold is one of the most efficient reflectors in the infrared region, particularly in the 2,000 to 12,000 nm range. This makes protected gold mirrors an optimal solution for systems that operate in infrared wavelengths, such as remote sensing, IR lasers, and thermal detection systems.

4. Broad IR Coverage:

   • 2000 nm to 12,000 nm: With excellent performance in both the mid and long-wave infrared ranges, these mirrors are suitable for applications across multiple infrared technologies, providing versatility in optical design.

5. High Environmental Resistance:

   • The protective dielectric coating significantly enhances the mirror’s resistance to moisture, oxidation, and chemical exposure, making these mirrors ideal for use in outdoor or humid environments, as well as in demanding industrial settings.

6. Customizable Options:

   • Size and Shape Customization: MOK Optics provides flexibility in design with a wide range of sizes and shapes to fit specific application needs.
   • Substrate Materials: A variety of substrate materials are available, including low-expansion materials like fused silica, which ensures thermal stability and minimal distortion at varying temperatures.

7. Low Scattering and Absorption:

   • The precision of the gold coating, combined with the protective layer, minimizes scattering and absorption, ensuring high efficiency and accurate light reflection, critical for precision optical systems.

8. Applications:

   • Thermal Imaging and Sensing: Protected gold mirrors are widely used in thermal imaging and IR sensor systems due to their excellent IR reflectivity.
   • Spectroscopy: The superior reflectivity in the infrared range makes these mirrors a preferred choice in spectroscopic instruments that operate at IR wavelengths.
   • Laser Systems: Their high reflectance in the IR spectrum enhances the performance of infrared laser systems, such as CO2 lasers used in medical and industrial applications.
   • Aerospace and Defense: In aerospace applications, these mirrors are essential for systems that detect IR radiation, such as missile tracking and satellite communication systems.

9. Precision Manufacturing:

   • Each protected gold mirror is manufactured to the highest standards, with stringent quality control to ensure consistent optical performance. Our advanced metrology lab tests for reflectivity, surface flatness, and coating durability.
