The HG-1 is a spectral wavelength calibration source specifically designed for UV-VIS spectrometers like our Jaz, USB2000, and HR series. The Hg-1 produces low-pressure mercury and argon emission lines from 250-1000 nm for use in performing fast, reliable spectrometer wavelength calibrations. The spectral emission lines are printed on the lamp's housing. Use a 50um UV-VIS fiber with SMA connector for best results
