110V Sodium Spectrometer Light Source

This 110V spectrometer light source provides predominantly monochromatic sodium light for spectrometry experiments. The unit features 2mm and 4mm holes plus a 4 x 20mm vertical slit, providing high uniform brightness across the measurement wavelength range for high signal-to-noise ratio photometric values. Made from high-quality materials for long service life. Suitable for physics classroom and laboratory spectrometry experiments studying light sources, refraction, and spectral analysis.
