WebThe Sellmeier equation is an empirical relationship between refractive index and wavelength for a particular transparent medium. The equation is used to determine the dispersion of light in the medium. It was first proposed in 1872 by Wolfgang Sellmeier and was a development of the work of Augustin Cauchy on Cauchy's equation for modelling ... WebApr 6, 2024 · See the Comparison tab for a side-by-side comparison of the wavelength-dependent transmission of N-BK7 and UV fused silica. These diffusers feature 120, 220, 600, or 1500 grit polishes. Our polishing process results in surfaces with significantly greater uniformity than those of sandblasted diffusers.

Refractive index of BK7 - SCHOTT

WebTraditional optical glasses (e.g., BK7, fused silica) are not considered good materials for cutting optical surfaces with single point diamond tools. The cutting mechanics result in a deep layer of subsurface damage that must be removed by polishing. The polishing renders the process too expensive for practical use. WebNov 24, 2024 · Therefore, it was a goal of the present experiments to locate the true mechanisms of high-aspect-ratio capillary channel formation in typical materials, such as PMMA and translucent fused silica glass K8 (which is an analog of Schott Glass BK7 glass) for a KrF laser in comparison with the drilling of highly transparent KU-1 glass … WebThese Plano-Convex Lenses are fabricated from RoHS-compliant N-BK7 and feature an antireflection (AR) coating that provides <0.5% average reflectance per surface over the 650 nm to 1050 nm wavelength range.
