How hollow cathode lamp works
Did you know?
WebA hollow cathode lamp works by using an electric current to heat up the cathode. This causes the gas inside the lamp to become ionized Step 2/2 and create a bright light. A … WebIn addition to dc operation, hollow cathode lamps may be operated by supplying pulsed current (at about 50–200 Hz) to increase the average amount of light that can be obtained from the lamp. Atomic absorption profile is the term used to describe the range of wavelengths over which it is possible for an atom to absorb radiation.
