UV-visible region transmittance filter standard material GBW(E)130314

Overall dimensions: ..
Nominal value of transmittance: %, %, %
Fixed value wavelength: .,.,.,.,.,.,.
Uncertainty of transmittance :.%
Complete set: One reference frame for each set.
Calibrating the transmittance accuracy and repeatability of the ultraviolet-visible spectrophotometer in the ultraviolet-visible light region can replace the currently used standard cuvettes, potassium dichromatate standard solution and neutral filter, and has a wide and medium spectral range. It has the characteristics of good stability, convenient use and accurate measurement.
