Refractive index bk7
WebN-BK7 is a very pure universal optical glass made by SCHOTT. It is one of the most common standard glass types used to produce high-quality optics, mainly for the visible spectrum. The relatively hard borosilicate crown material consists of the purest raw ingredients. It contains very few inclusions and is almost free of bubbles. 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 …
