What are Silicon Mirrors?
Silicon mirrors are precision optical components made from high-purity silicon, valued for their excellent reflectivity in the infrared (IR) spectrum and thermal stability.
Often coated with metallic or dielectric layers, they enhance reflectivity and durability for specific applications.
Silicon mirrors are widely used in laser systems, spectroscopy, and IR imaging, offering lightweight yet robust performance. Their high damage threshold and ability to withstand extreme temperatures make them ideal for industrial, scientific, and aerospace applications.
What is a Silicon Mirror Made Of?
A silicon mirror is made from high-purity silicon, known for its excellent thermal stability and infrared reflectivity. Often coated with metallic or dielectric layers, it’s ideal for IR laser systems, spectroscopy, and thermal imaging.
Silicon is a commonly used optical glass material in the infrared band. The transmission band is 1.2-8.0μm. Silicon has high thermal conductivity. It can be used as the substrate for a variety of optical components, such as lenses, windows, etc.
It is often used in near-infrared and mid-infrared applications, and is also suitable for infrared imaging, terahertz imaging, medical, military and other applications.
