Wavelength Verification Standard: SL2

The SL2 fiber optic cal lamp provides Mercury
and Argon gas emission lines which are
utilized to verify or calibrate spectrometer
wavelengths from 253.65 to 1013.98nm.
¾ The lamp is designed so that the lowpressure 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.
¾ Portable operation is available from a
standard 9 Volt DC battery (not included).
The SL2 also includes a 5 Volt DC wall
adapter for 120 Volt AC, U.S. style
transformer and plug. Operation outside U.S.
requires SL2-Y-cable or UP5V adapter.
Note: the StellarNet spectrometers are wavelength
calibrated at the factory using the SL2 and additional
emission line sources. These instruments are
ruggedized for portability and never need to be recalibrated. The SL2 can be used to easily verify any
wavelength readouts.
