At Artifex Optics we are committed to continue serving the growing demands of the optics community by supplying superior optical components and assemblies, from the simple to the most advanced, in prototype and production quantities. .An optical flat is a precisely polished flat surface which may be used as a reference to measure the flatness of an unknown surface. Artifex Optics offers both single surface and dual surface optical flats in BK7, Zerodur or Fused Silica. We offer two different levels of accuracy: λ/10 and λ/20 for our single surface optical flat. For our dual surface optical flat, λ/10 is available. We provide a Zygo® test report with each flat. For more information, please visit our website http:.//www.artifex-optics.com ®Zygo is a registered trade mark of Zygo corporation.

Application Notes: Interference fringes formed between an optical flat and a device under test when viewed under monochromatic light give a visual representation of the flatness of the surface being tested. The surface accuracy is indicated by the amount of curvature and spacing between the interference fringes. Measurement of the surface flatness of polished surfaces can be determined visually by comparing the variations between a work surface and the surface of an optical flat. These are versatile optical components used in many applications such as: inspection of gauge blocks for wear and...
