Product Name:Optical Flat
Item No.: FA001
Description:Flat mirrors are smooth, highly polished, flat surfaces, 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 ellipse. We especially specialize in production of medium to large-size series of custom mirrors with exacting tolerances, high grade surface finish and difficult coatings. Surface accuracy is verified on the Zygo interferometer or Wyko interferometer. Our optical designers are always available to assist with your special needs and our production in China is ready to meet your quantity requirements.
