LED, picosecond & calibration sources
Wavelength Calibration Lamps
Mercury and mercury–neon line sources for checking the wavelength scale of a spectrometer. Choose a calibration-lamp assembly to match the entrance slit and the emission lines required by the instrument.

Best suited to
Spectrometer wavelength calibration and verification with discrete reference emission lines.
Selecting a configuration
Match the lamp spectrum and mechanical interface to the spectrometer. LSH-HgNe-A fits motorised slit arrangements; LSH-HgNe-B fits manual slit arrangements.
Measurement & configuration
- Mercury emission lines cover UV and visible wavelength references.
- Mercury–neon assemblies extend the set of available reference lines.
- Source-specific lamp mounting for compatible spectrometer entrances.
