What is the difference between SCHOTT Nexterion® Glass B and D?
Nexterion® Glass B is a borosilicate glass that is produced by the microfloat process, resulting in a top fire-polished surface; and a lower surface that has been in contact with the molten tin. On customer request SCHOTT indicates which is the top (fire polished) side of the Nexterion® Glass B slides, and all the slides are kept in the same orientation throughout processing and packing. The refractive index of Glass B is 1.47 (nd λ = 546nm and ne λ = 588nm). Nexterion® Glass D is also a borosilicate glass but it is produced by a special down-draw production process that results in two fire-polished surfaces that can be used without any additional processing. The refractive index of Glass B is 1.52 (nd λ = 546nm and ne λ = 588nm).
