What is the wavelength range of xenon arc lamp?
A xenon arc lamp is used because of its stable intensity throughout the wavelength range from 200 to 800 nm, covering the UV/vis absorption of flavins.
What is a xenon arc lamp used for?
Xenon-mercury short-arc lamps have a bluish-white spectrum and extremely high UV output. These lamps are used primarily for UV curing applications, sterilizing objects, and generating ozone.
What is the spectrum of xenon?
Even though xenon lamps produce broadband, almost continuous emission having a color temperature approximating sunlight in the visible wavelengths (often referred to as white light), they do exhibit a complex line spectrum in the 750 to 1000 nanometer region of the near-infrared spectrum (see Figure 1).
What is a short arc lamp?
A short arc lamp is generally a spherical or slightly oblong quartz bulb with two electrodes penetrating far into the bulb so that the tips of the electrodes are only a few millimeters apart. An arc is formed between these electrodes. The bulb is filled with xenon, mercury vapor, or a mixture of these at high pressure.
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.
Who invented xenon arc lamp?
Osram
➢Then xenon short-arc lamps were invented in the 1940s in Germany and introduced in 1951 by Osram.
Do Xenon lamps contain mercury?
Why is xenon used in lights?
The xenon gas amplifies the brightness of the light, which helps it quickly reach the temperature required to emit a high-intensity beam.
How do you dispose of xenon lamps?
Xenon bulbs are safe for regular disposal in your black bin and curbside trash collection. Bag them to ensure broken glass doesn’t spread and throw them in the trash bin for disposal with your household waste.
Why is a xenon arc lamp used in fluorescence?
Fluorescence Spectroscopy A xenon lamp is well used as an excitation source because it emits photons of a wide range of wavelengths. The light of the xenon lamp is separated through a monochromator into various wavelengths.
Are xenon bulbs recyclable?
Xenon bulbs are safe for regular disposal in your black bin and curbside trash collection.
Do car headlights have mercury?
Mercury vapor is used in the light sources for the headlights. There are two light sources per vehicle, and each light source contains 0.0005 to 0.001 grams of mercury .
How long do xenon bulbs last?
Xenon headlights last a lot longer than halogen ones – 2,000 to 2,500 hours for xenon headlights compared to 400 to 1,000 for halogen.
