Flat Mirrors are high-precision optical components for beam deflection, interferometry and imaging systems. Crafted with advanced vacuum nano-coating, their surfaces are coated with metal/dielectric films to form high-performance reflective layers, enabling efficient light reflection and stable imaging.

AOS Optics’ Flat Mirrors feature a planar reflective surface, with 1700mm as our maximum customizable size—we welcome your inquiries for large-diameter requirements. We also offer custom flat mirrors in round, square and elliptical shapes to match diverse application needs.
The core performance parameters of our Flat Mirrors are surface accuracy and reflectivity. High-precision surface finish effectively reduces light loss caused by dispersion; our optical mirrors adopt premium high-reflectivity first surface reflection technology, delivering an average reflectivity of over 98%. This advanced design ensures clear, distortion-free imaging with high definition and no ghosting, eliminating the optical interference of secondary reflection.
Engineered for professional light reflection applications, our Flat Mirrors are widely used for beam control, interferometry, imaging and lighting scenarios. They are essential optical components across key industries including life sciences, astronomy, metrology, semiconductors and solar energy.
We provide flexible coating options for our Flat Mirrors, including coated and uncoated versions. Our standard coating range covers protected aluminum, protected UV reflective aluminum, protected silver and protected gold; for UV band applications, we offer fused silica substrates for optimal optical performance.
