WebIn refractiveor diffractiveoptical systems, especially those imaging a wide spectral range, coma can be a function of wavelength, in which case it is a form of chromatic aberration. Overview[edit] Coma is an inherent property of telescopes using parabolic mirrors. WebFlare caused by scattered light in the projection optics could result in several nanometers of on-wafer dimensional variation, if left uncorrected. Previous work by the authors has focused on combinations of model-based and rules-based approaches to modeling and correction of flare in EUV lithography. how many bricklin sv-1 were made https://northernrag.com
