Far UV Range Quartz Cells & Spectrophotometer Cells
Spectrocell’s far UV range quartz cells and spectrophotometer cells are used for tests that are being conducted in the visible wavelengths only, that is, from 170-2200 nanometers.
What’s the Difference Between Quartz Cell Materials?The terms “fused silica,” “fused quartz,” and “quartz glass” all refer to glass composed of greater than 99% silicon dioxide (SO2). The only difference between them is how the material is produced.
Fused quartz refers to quartz glass made from naturally occurring quartz crystal. These crystals are mined and cored to obtain their relatively pure centers, which are then melted in an electric arc furnace. The melting process breaks down the crystalline structure and produces a completely isotropic quartz glass, meaning there is no preferred optical axis, as is the case with crystalline quartz.
Fused silica is made from pure silicon dioxide powder, either in an electric arc furnace or a melt tower. The result is the same, a completely isotropic quartz glass of very high purity.
The quartz glass that results from either process is the hardest glass available. It is more inert and chemically resistant than any other type of glass. Quartz glass’s optical properties are excellent and, unlike other glasses, this material continues to transmit into the UV range. (Click here for a comparative transmission chart). Quartz glass is also much more thermally stable and resistant to thermal shock than softer glass.
Spectrocell’s Far UV Range Quartz Cells & Spectrophotometer CellsOur far UV range quartz cells and spectrophotometer cells are manufactured from FUV grade quartz glass. This material provides 82% transmission from 170 to 2200 mm, and is the best choice for tests within that range.
We also offer NIR grade quartz glass cells, which provide 84% transmission at 2700 mm for tests in the NIR range. Overall transmission is 220 to 3500.
