Calibrators, Spectrophotometer, Visible Light

Definition : Spectrophotometer calibrators designed for verification of the transmittance and/or absorbance scales of visible spectrophotometers. These calibrators typically consist of a set of filters (e.g., holmium oxide, didymium oxide) with different nominal transmittance values (e.g., 10, 20, 30%); each filter is calibrated stating the transmission values at several frequencies in the visible range (e.g., 440.0, 546.1, 635.0 nm).The filters are usually mounted in a cuvette-size holder to facilitate calibration.
