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 ... WebWhen compared to N-BK7, UV fused silica is transparent over a wider range of wavelengths (185 nm - 2.1 µm) and also offers a lower index of refraction as well as better homogeneity.

WebApr 29, 2024 · In addition, UV fused silica has better homogeneity and a lower coefficient of thermal expansion than N-BK7. Plano-convex lenses can focus a collimated beam or collimate light from a point source. To minimize the introduction of spherical aberration, a collimated light source should be incident on the curved surface of the lens when being ... WebFor example, the often used BK7 glass is a crown glass (see below) of that type. Borosilicate glasses are chemically quite resistant, if the boron content is not too high. Compared with fused silica, they have a lower (although still relatively high) melting temperature, which makes them simpler and therefore cheaper to process. grasshopper shoes for women locations
