Calibration Filter Set for UV-VIS Spectrophotometer
Calibration Filter Set for UV-VIS Spectrophotometer DownloadCalibration Filter Set for UV-VIS Spectrophotometer
The set 666.000 consists of neutral density glass filters for testing the absorption values and a holmium oxide glass filter for testing the wavelength accuracy. The glass filters are mounted in precision frames of aluminium. They are designed such that they fit into the holders for standard cuvettes with a 10 mm light path with which the spectrophotometer is equipped. The set is delivered together with an empty filter frame as reference in a sturdy box.
For purposes of identification, the set number is engraved on each filter frame. The measured values of the absorption and the wavelengths are shown for each filter in the calibration certificate supplied. For purposes of working in the laboratory, the measurement values are also shown on the inside of the lid of the box.
