HCL

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).
