Description

The hydrogen spectral tube, used with its power supply as shown, is viewed individually by students holding standard replica grating, but is necessary because the hydrogen tube is not very bright. Please collect the holographic gratings; they are a bit more pricey than the hand-held replica gratings cut from a roll of material
