Photron Hollow Cathode Lamps

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).
