What is a hollow cathode lamp?

The

hollow cathode lamp is a light source primarily used for scientific purposes. In fact, these lamps do not exist outside the laboratory environment, which means that most people will never see it. Usually, a hollow cathode lamp is used as a tuning method in specific light frequencies. These frequencies are used to examine the composition of materials and tune in light -based systems such as lasers. Depending on the materials used in their construction, the gases were pumped into them and the external influences may be lit by a hollow cathode lamp with almost any color of the spectrum. Most of these lamps consist of four main parts. The anode and cathode deal with power and release it. They are associated with a large glass tube, which is filled with a fabric called buffer gas. This gas can be any form of inert gas, usually noble gas such as neon, helium or argon.

When powering to the lamp over the anode, it moves and moves the gas to the cathode. It begins to excite the buffer plyn and turns into plasma. Plasma bombes the cathode and induces a process called spraying. This is when high -energy particles knock atoms from a fixed object. These sprayed atoms and plasma will become more and more and more and gain energy.

When the energy begins to distract, the materials begin to emit photons. These photons are light generated by a lamp. Different materials emit different wavelengths of visible light. The spectrum of photons can be analyzed to determine the accurate composition of gases and sprayed materials. This process can be used to analyze the composition of unknown material or verify the existence of the substance in the sample.

In addition, the hollow cathode lamp can be used to tune in specific wavelengths. When a GHT -based prescription is designed in certain parameters, the initial use of energy and wavelength settings are often tested on one of these lamps before passingto the lighting system. This is primarily a problem with costs; Designed systems are often very complex and expensive, so parameters are tested on cheaper lamps.

In this case, the hollow cathode lamp is set to use the same materials used in a light -based system. As the power flows through the lamp, the wavelength of the light is examined. As soon as the power supplied to the system rises up and down, the wavelength changes. Using this method, scientists are able to determine accurate energy requirements and materials needed for a larger system than they actually create.
