WebMay 1, 2010 · The facility allows to produce an optical surface of any complex (convex/concave) shape, including higher-order aspheres with an asymmetrical profile and a diameter of up to 300 mm, with a subnanometer precision of the surface shape and the effective roughness in the range of spatial frequencies q∈[2.5·10 −2 –6.0·10 1 μm −1] … WebOct 6, 2024 · This topic seeks to develop a polishing and finishing method for conformal window materials that improves upon the time, cost, and quality of existing processes. The polishing and finishing process developed in this effort should demonstrate a 2-3x reduction in lead time compared to existing processes. Relevant geometries should include ...
Understanding Surface Quality: A Practical Guide - Photonics
WebSurface polishing is accomplished by rastering or rotating the optic through the fluid. The MRF tool can be used for final figure corrections on optics and is used to imprint a diffractive pattern onto the continuous phase plates (CPPs) prior to final use. Researchers Selected Publications Paul Ehrmann Joe Menapace Gary Tham Finishing science WebUnderstanding Surface Roughness. Surface roughness is one component of describing how the shape of a surface deviates from its ideal form, where higher values correspond to rougher surfaces while lower values indicate the surface is smooth. Roughness describes high spatial frequency errors, meaning very small deviations on the order of ... panty taille haute gainant
