WebThe working principle of optical flats is based on the principle of interference. Before allowing a monochromatic light to pass through the area of contact, an optical flat is placed on the surface to measure its flatness. There will be no gap between the two surfaces if the test surface is perfectly flat. In cases where the test surface is not ...
