How hollow cathode lamp works
WebA hollow-cathode lamp (HCL) is type of cold cathode lamp used in physics and chemistry as a spectral line source (for example, in atomic absorption spectrometers) and as a frequency tuner for light sources such as lasers. WebAs it uses a hot cathode to achieve stable and reliable arc discharge, approximately 10 sec for preheating is required before starting the discharge. A deuterium lamp requires a large and complex power supply, making it more expensive than a halogen lamp.
