Silicon Semiconductor Supermirrors

• Lowest Mechanical Loss and Highest Thermal Conductivity of Any Current Supermirror Technology
• Optical Loss Less Than 200ppm
• Microroughness of Approximately 3Å

Silicon Semiconductor Supermirrors provide excess optical losses (scatter and absorption) as low as 200ppm in the mid-IR spectrum (3 - 4μm). Featuring a single-crystal optical interference coating, these supermirrors offer a robust reflecting surface that does not easily degrade. These Silicon Semiconductor Supermirrors won a Prism award in the category of Materials and Coatings for their mid-IR coating technology. Semiconductor supermirrors are ideal for industrial applications in cavity ring-down spectroscopy, metrology, manufacturing, and sensing.
