The product is a high-performance silicon-based plano-concave mirror designed specifically for the 10.6μm infrared band (e.g., CO₂ laser systems). Utilizing high-quality monocrystalline silicon (Si) as the substrate, combined with a precision plano-concave surface design and advanced multilayer dielectric coating technology, it achieves highly efficient optical path deflection and focusing. It features an extremely high laser-induced damage threshold and excellent thermal stability, making it widely applicable in medical laser equipment, industrial laser processing, and precision infrared optical systems.
