Glass Mirror is an optical component made from high-quality glass substrates coated with reflective materials such as aluminum, silver, or dielectric multilayer coatings. It is manufactured through precision polishing to achieve high surface flatness and low scattering characteristics. These mirrors are widely used in laser systems, telescopes, imaging equipment, and optical alignment setups. They provide controlled beam reflection with minimal distortion and energy loss. Glass mirrors are essential components in optical path design, enabling accurate beam steering and signal direction control in both industrial and scientific applications.
