HCL: Ca/Mg Multi-Elements 37 mm, coded (P870C)

Hollow cathode lamps produced by Photron are designed and manufactured to achieve all of the following fundamental requirements for a spectral line source.

- Intense emission of resonance (ground state derived) lines.

- Narrow line width, for maximum sensitivity and linearity.

- Minimal spectral interference from continuum emission, present in the cathode.

- Rapid warm up to produce stable long term light emission.

- Noise free operation.

- Long running life and a 5 year shelf life.

- Cathode materials and geometry achieve a combination of spectral purity and a suitable sputtering rate. (A high sputtering rate will give high intensity at the expense of lamp life, sensitivity and linearity).
