Wavelength Calibration and VerificationSL2 Mercury Argon
Wavelength Calibration and Verification 
The SL2 Mercury Argon Light Source provides accurate gas emission lines which can be utilized to verify or calibrate spectrometer wavelengths from 253.65 to 1013.98nm.
Convenient – The lamp is designed so that the low pressure emissions enable quick and accurate calibrations. A labeled chart provides spectral emission lines for Mercury and Argon at various wavelengths for easy and quick reference.
Portable – Miniature size 0.75 x 2.5 x 4.5″ provides ultimate portability with 9 Volt DC battery operation makes the SL-2 perfect for field verifications is available from a standard 9 Volt DC battery (not included). The SL2 also includes a 5 VDC wall adapter for 120 Volt AC, U.S. style transformer and plug. Operation outside U.S. requires UP5V adapter.
Note: the StellarNet spectrometers are wavelength calibrated at the factory using the SL2 (Mercury Argon), SL6 (Neon), and additional line emission sources. These instruments are ruggedized for portability and are guaranteed accurate within 1/4nm. The SL2 can be used to easily verify any wavelength readout and confirm spectral calibration.
