Therefore, it’s useful for almost anyone involved in the specification and purchase of optical components to have some familiarity with the typical performance characteristics, trade-offs and limitations of various coating types, as well as some knowledge of the capabilities of common thin-film production technologies. This article provides an objective overview of both these topics.What are thin-film coatings? The purpose of any optical thin-film coating is to modify the transmittance and reflectance properties of the substrate material to which they are applied. Most coatings...Photonics HandbookGaussian and Newtonian Thin Lens Formulas: Four important equations from which the image distance and the lateral magnification can be computed for an object at any arbitrary distance from a thin lens.Equation (1) is known as the Gaussian form of the lens equation, after the mathematician Karl F.
