WebAug 30, 2008 · A simple easy device for measuring the refractive index of solids by using a laser beam with maximum deviation from a prism was derised. The refractive indices of four kinds of transparent optical glasses (BK7, F2, SF10, SFL11) were measured using the new device and an existing prism spectrometer with a He-Ne laser (λ = 632.8 nm) and a YVO 4 … WebAug 2, 2024 · BK7 is an OK material to use for most applications. I would use it for standard applications in the visible spectrum. For off-the-shelf optics, the cost is often 20-30% less than for UV grade fused silica. This adds up when considering buying a large set of optics. Share Cite Improve this answer Follow answered Mar 30, 2024 at 0:44 Ru887321 256 1 5
WebFor example, BK7 has a refractive index of 1.5228 at 480 nm (blue) and of 1.5131 at 700 nm (red). That basically means that if we have a biconvex lens made with BK7, it will focus red and blue light at different points, resulting in chromatic aberration. This is shown in Figure 1. FIGURE 1. 50MM Chromatic Aberration on a Biconvex Lens WebThe refractive index n of a medium (e.g., water, olive oil, etc.), also called the index of refraction, is defined as the quotient of the speed of light in vacuum c and the speed of …
WebMay 30, 2024 · For binoculars, spotting scopes, and monoculars, BaK-4 is generally preferable to BK-7 or K9 as it has a higher refractive index and, when used in a well-designed overall optical system, provides higher levels of image quality than would a prism assembly of the same type made with BK-7 or K9 glass. It is often written that the exit … WebThe Abbe number, V d, of a material is defined as =, where n C, n d and n F are the refractive indices of the material at the wavelengths of the Fraunhofer C, d, and F spectral lines (656.3 nm, 587.56 nm, and 486.1 nm respectively).This formulation only applies to the visible spectrum.Outside this range requires the use of different spectral lines.
