SL2 Wavelength Verification Standard for UV-VIS-NIR • Calibration Source- Verify or calibrate spectrometer • Convenient Operation- Includes U.S. style 5 Volt DC output power adapter for AC supply and optical fiber to check any spectrometer • Portable- Miniature size 0.75 x 2.5 x 4.5 inch provides ultimate portability with 9 Volt DC battery operation makes the SL-2 perfect for field ^ The SL2 fiber optic cal lamp provides Mercury and Argon gas emission lines which are utilized to verify or calibrate spectrometer > 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 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. 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 re- calibrated. The SL2 can be used to easily verify any wavelength readouts. _hl±J sJU±J«lml*JjiJ SL2 Light Emission Graph of HgA line Spectra Light Sources and Fiber Optic Accessories
