Spectral Lamps with Power Supply
For observing line spectra of sodium and mercury. Black metal housing on shaft with integrated power supply and threaded light aperture for direct mounting of filters.
For experiments with Hg spectral lines of high intensity. Lines in the UV region are suppressed by the glass body.
Light aperture: 40 mm Ø
Filter thread: M49
Dimensions: 242x153x80 mm
