Results...PHOTONICS HANDBOOK ARTICLESPhotonics HandbookThin-Film Coatings: A Buyers' Guide: The vast majority of optics used in precision scientific, industrial, biomedical, and military applications incorporate thin-film coatings on their surfaces. 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 HandbookOptical Coating: Materials and Deposition Technology: Surface coatings used to control optical, mechanical and electrical properties are deposited as nano- and micrometer thicknesses of special materials.Optical coatings are deposited as thin-film multilayers of a variety of materials using specific deposition techniques.

Laser manufacturers are responding with products optimized to match the needs of these applications.Laser development for the microscopy market continues to be driven by key trends in applications, which currently include superresolution techniques, multiphoton applications in optogenetics and...Photonics HandbookMirrors: Coating Choice Makes a Difference: A mirror is an important element in many optical systems. Its basic function is to redirect light, often with the purpose of making an optical system more compact. This article discusses the kinds of thin-film coatings that can be used for mirrors. The choice of coating depends on the application, including the spectral range of interest, the optical wavefront quality desired and the cost limitations.The basic difference between the household mirror and the optical mirror is that one is coated on the back surface and the other is coated on the front. For optical applications, a front-surface...WHITEPAPERSPhotonics.com 12/10/2021Characterization of Dry Electrolyte Polishing ProcessThe preservation of the form is demonstrated by complementary form measurements using Ai Focus Variation technique.
