Dual spectral power pack + Hg-Na bulbs (E27)

Mercury and Sodium bulbs are the most commonly used.

Sodium provides both a quasi-monochromatic reference and a doublet, while Mercury offers distinct lines that are clearly visible for calibration purposes.

This kit offers an integrated set with a dual-output power supply for a simple and transportable solution.
