The compact, low-cost HG-1 Mercury Argon Calibration Source is a spectral wavelength calibration source for UV-VIS-Shortwave NIR spectrophotometric systems. The HG-1 produces mercury and argon lines from 253-1700 nm for use in performing fast, reliable spectrometer wavelength calibrations. Easily identifiable mercury and argon spectral emission lines are printed on the HG-1 housing. The HG-1 features an SMA 905 Connector to couple to Ocean Optics spectrometers and fiber optic accessories, including optical fibers. The HG-1 operates with a 12 VDC power supply (included with the unit) or 9V battery (not included).
