Abstract

CADCAM system is very vital in the development and production of high efficiency optical coatings, in which in-situ analysis and optiniizatfrxi is the nucleus. A new algoritlin for in-situ analysis and optimization of coatings has been proposed, which has provision for precise determination of optical parameters, namely refractive index n, and gearetrical thickness d, of any layer :tt the multilayered configuration and, to account for adverse effect of the deviaticxs in the optical pareters through global re-optimization of the coatings. It has been implemented on 8086/8087 microprocessor systn in which 8086 is a 16 bit microprocessor and 8087, a coprocessor for high speed floating point operatixs. The validity of the algorithn has been established through a wide range of hypothetical case studies and experimental deve1opint of a few coatings such as wideband antireflecticx coatings (ARCs).
