Deuterium lamps are the preferred source for UV spectroscopy

Deuterium Light Sources offer a continuous UV spectrum that is ideal for use on spectroscopy.

Deuterium lamps create an arc between the anode and tungston filament that excites molecular deuterium. Light is emmitted as it transitions back to it's initial state. The intense continuum from the vacuum ultraviolet to 500 nm, and the low visible and infrared output, ensure superior signal to noise for many UV measurements.

We stock a number of different models from Heraeus, Hamamatsu and others, including part numbers: L1789, DO801, DO302, DO902, D1050, R.23, G.03, 3UNXGa, 5QN/Cu-Zn, Cu, Pb, As and Hollow Cathode.
