Spectral tubes (Plücker tubes) are the most economical solution for studying line sources. Their fine and vertical emissive shape allows for easy spectrum creation. Warning: some tubes wear out quickly. To maintain a lifespan of around a hundred hours, we recommend respecting lighting cycles with a maximum duration of 10 minutes (see timer below). Completely secure thanks to its circuit-cutting protective cover, the robust power supply will bring you satisfaction and ease of use. To be completed with spectral tubes.
