Mirror

As a core control component of optical systems, the optical mirror precisely adjusts light path direction, focuses energy, or enables imaging based on the law of reflection, serving as a key link between light and its applications.
It adopts ultra-precision processed substrate materials (such as fused silica, silicon carbide) and custom coating technologies to create high-performance reflective surfaces: metal coatings (aluminum, silver, gold) adapt to different wavelength requirements from ultraviolet to far-infrared, while dielectric coatings can achieve ultra-high reflectivity of over 99.9% with extremely low loss. By strictly controlling surface roughness (some products have RMS < 0.8 Å) and surface figure accuracy (up to λ/20 level), it effectively reduces light scattering and ensures precise, distortion-free light paths.
Available in various forms including planar, spherical, and aspherical, it can be customized for scenarios such as laser resonators, astronomical observation, semiconductor manufacturing, and biological imaging. With high laser damage threshold and environmental stability, it provides reliable support for precision optical systems.
