一般描述
Certified liquid Hellma® calibration standard to enable the checking of spectrophotometers with respect to wavelength accuracy
The Diymium filter consists of a solution of Praseodymium and Neodymium dissolved in perchloric acid. This filter is highly suitable for checking the wavelength accuracy of spectrophotometers both in the UV and the visible range. In the range between 329 nm and 864 nm the filter shows a spectrum with a multitude of highly defined and characteristic peaks. .
Consisting of :
Didymium in perchloric acid (667-UV25, wavelength 329; 469; 575; 740, 864 nm)
