Metal Coating Mirrors are produced by depositing metallic reflective layers onto precision-polished glass or fused silica substrates using vacuum coating techniques. The optical performance depends on reflectivity curve, coating adhesion strength, and substrate flatness. These mirrors are designed for broadband reflection across visible and infrared spectra, making them suitable for optical path steering, imaging systems, and laser alignment setups. Surface quality and coating uniformity are critical for minimizing scattering losses.
