• SL2 Mercury and Argon standard: $275
• SL2-Y-cable (Shares +5VDC from spectrometer): $15

The SL2 Wavelength Verification Standard is designed for UV-VIS-NIR spectrometer calibration, covering wavelengths from 253.65 to 1013.98 nm. It includes a calibration source for verifying or calibrating spectrometer wavelengths.

• Convenient Operation: Comes with a U.S. style 5 Volt DC output power adapter and optical fiber for spectrometer checks.
• Portability: Compact size (0.75 x 2.5 x 4.5 inches) and 9 Volt DC battery operation make it suitable for field verifications.

• Weight: 0.2 lbs (85 grams)
• Connectors: SMA-905 and +5 VDC
• Power Consumption: 100ma
• Battery Operation: +9 VDC (optional)
• Spectral Range: 253.65 to 1013.98 nm
• Time to Stabilize Output: 15 seconds

The SL2 uses Mercury and Argon gas emission lines for spectrometer wavelength verification or calibration. It provides quick and accurate calibrations with a labeled chart for easy reference of spectral emission lines.

Operates with a standard 9 Volt DC battery (not included) or a 5 Volt DC wall adapter for 120 Volt AC. For operation outside the U.S., an SL2-Y-cable or UP5V adapter is required.

StellarNet spectrometers are factory-calibrated using the SL2 and other emission line sources, ensuring rugged portability and eliminating the need for re-calibration. The SL2 can verify any wavelength readouts easily.
