Product Description

667-UV5 Filter for Testing Wavelength Accuracy

-          Wavelength : 241, 287, 361, 536, 640 nm

-          Delivered with NIST traceable DAKKS certificate

General description Certified liquid Hellma® calibration standard to enable the checking of spectrophotometers with respect to wavelength accuracy.

Consisting of :
Holmium oxide in perchloric acid (667-UV5, wavelength 241; 287; 361; 536; 640 nm)

Holmium oxide dissolved in perchloric acid is highly suitable for checking the wavelength accuracy of spectrophotometers both in the UV and the visible range. It shows a spectrum with a multitude of highly defined peaks. The heights and positions of these peaks are dependent on and will vary with the chosen slit width of the measuring instrument.
