|Flat mirrors are smooth and highly polished. The flat surfaces are used for reflecting light. The actual reflecting surface is usually a thin coating of silver, aluminum, or other material. They may be fashioned from a number of materials, including BK7 glass, copper, fused silica, UV grade fused silica, nickel, and optical crown glass. |
Flat mirrors we provide either come round, square, rectangular or elliptical. We specialize in the production of medium to large-size custom mirrors with exacting tolerances, high grade surface finishes and difficult coatings. The surface accuracy is verified on a Zygo or Wyko interferometer.
