Ocean Optics HG-1 Mercury Argon Calibration Source
The compact, low-cost HG-1 Mercury Argon Calibration Source is a wavelength calibration standard for UV, Vis and near-IR regions of the spectrum. The HG-1 produces first order mercury and argon emission lines from 253-922 nm and second order argon emission lines to 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 can be used to verify the wavelength accuracy of any spectrometer and can be used to recalibrate Ocean Optics spectrometers, if necessary.
The HG-1 operates with a 12 VDC power supply (included with the unit) or 9V battery (not included). Use any SMA 905 fiber optic cable to connect with the HG-1.
- Primary standard requires no calibration or verification with strong lines in the UV to near-IR
- Easy-to-use with calibration lines printed on the lamp housing
- Portable with 9V battery optional for power supply
- 12 VDC Power Supply
