What is xenon light source?
Xenon light sources offer very high intensity in the UV and are useful for absorbance, fluorescence or reflectance measurements. Pulsed xenon sources are high intensity with a lower duty cycle, making them ideal for measurements where high intensity UV light can damage the sample.
What is the wavelength of xenon lamp?
The light produced by the xenon lamps includes broad-spectrum wavelengths from 100 to 1100 nm (Figure 1): UV light (100–400 nm), visible light (400–700 nm), and near-infrared light (700–1100 nm).
Which gas is used in xenon lamps?
xenon gas
Xenon short-arc lamps come in two distinct varieties: pure xenon, which contains only xenon gas; and xenon-mercury, which contains xenon gas and a small amount of mercury metal.
Does xenon emit UV light?
Xenon lamps, which are almost always used in solar simulators, emit a dangerous amount of UVR. Without appropriate safeguards the radiation on uncovered skin soon leads to burns, eye damage, and permanently enhances the risk for cancer.
How do xenon lamps work?
A xenon arc lamp is a special type of gas discharge lamp. Xenon arc lamps produce light by passing electricity through ionized xenon gas at high pressure. It produces a bright white light that closely mimics natural sunlight, which extends its applications into the film, and daylight simulation industries.
Do Xenon lamps contain mercury?
XENON pulsed UV lamps do not contain mercury, a known toxic material. Pulsed UV lamps do not generate potentially dangerous microwaves.
Do xenon lamps contain mercury?
Where is xenon found?
Xenon is present in the atmosphere at a concentration of 0.086 parts per million by volume. It can also be found in the gases that evolve from certain mineral springs. It is obtained commercially by extraction from liquid air.
How do xenon arc lamps work?
How does xenon bulb work?
The electrical current hits the electrodes, creating a powerful electrical force. The electricity causes the xenon gas atoms to split into smaller parts (ionization) The ionization process causes the atoms to split into positively charged ions and negatively charged electrons.
How is xenon obtained?
Xenon is obtained commercially as a by-product of the separation of air into oxygen and nitrogen. After this separation, generally performed by fractional distillation in a double-column plant, the liquid oxygen produced will contain small quantities of krypton and xenon.
How do you dispose of xenon lamps?
Halogen, incandescent, and LED bulbs are not hazardous and can be disposed as garbage. High-intensity discharge bulbs (HID, Xenon, Plasma, or Arc) contain hazardous mercury and must be recycled at a free drop-off mercury lamp recycling site.
