  Xenon Flash Lamp - General Information
Xenon flash lamp cleaning vaporizes organic coatings by using intense pulsed light energy.
Xenon flash lamp cleaning may be used in conjunction with other techniques so that, as the coating is ablated by the flash lamp, the substrate is protected from overheating.
As the coating is ablated by the flash lamp, the pellets simultaneously cool the thin substrate and remove the residue.

  Xenon flash lamp
The lamp is comprised of a sealed tube, often made of fused quartz, which is filled with a mixture of gases, primarily Xenon, and electrodes to carry electrical current to the gas mixture.
Because the duration of the flash that is emitted by a Xenon flash tube can be accurately controlled, and due to the high intensity of the light, xenon flash lamps are most commonly used as photographic strobe lights.
Xenon flashlamps are also used in the technique of very high speed or "stop-motion" photography, which was pioneered by Harold Edgerton in the 1930's.

A xenon flash lamp is a gas discharge lamp (additional info and facts about gas discharge lamp) designed to produce extremely intense, incoherent (additional info and facts about incoherent), full-spectrum white light for very short durations.
The lamp is comprised of a sealed tube, often made of fused quartz, which is filled with a mixture of gases, primarily xenon (A colorless odorless inert gaseous element occurring in the earth's atmosphere in trace amounts), and electrodes to carry electrical current to the gas mixture.
Xenon flashlamps are also used in the technique of very high speed or "stop-motion" photography, which was pioneered by Harold Edgerton (additional info and facts about Harold Edgerton) in the 1930s (The decade from 1930 to 1939).

 Xenon Flash Thermal Diffusivity System
In this method, a short pulse (less than 1 millisecond) of heat is applied to the front face of a specimen using a xenon flash lamp, and the temperature change of the rear face is measured with an InSb infrared (IR) detector.
The xenon flash thermal diffusivity system is optimized for room-temperature measurements.
The xenon flash thermal diffusivity system has been used in the study of factors affecting the properties of materials, such as processing conditions, composition, heat treatments, sintering aids and dopants, composite structure, grain size, and porosity.

A compact fluorescent lamp with an integrated electronic ballast A fluorescent lamp is a type of lamp that uses electricity to excite mercury vapor in argon or neon gas, resulting in a plasma that produces short-wave ultraviolet light.
In contrast with all other electrical lamps that use electrical connections through the lamp envelope to transfer electrical power to the lamp, in electrodeless lamps the power needed to generate light is transferred from the outside of the lamp envelope by means of (electro)magnetic fields.

 Xenon flash lamp - Wikipedia, the free encyclopedia
Depending on the size and application of the flashlamp, xenon fill pressures may range from a few kilopascals to tens of kilopascals (0.01–0.1 atmosphere or tens to hundreds of torr).
However, for xenon, there are enough spectral lines, and they are distributed across the spectrum in such a way, that to the human eye the light appears white.
The flash that emanates from a xenon flash lamp may be so intense, that it can ignite flammable materials within a short distance of the tube.

 Flash lamp power supply with direct energization from an AC power supply source - Patent 4041351
This xenon flash lamp may be formed in the shape of a rod where it is disposed in a partially enclosed mirrored surface with the laser light producing means.
When the flash lamp 313 is initially fired, the charge on the prepulse capacitor 308 and aging capacitor 326 will add to the initial current surge through the flash lamp 313 and will produce a high narrow current peak at the beginning of the firing of the lamp.
The current flow from the prepulse capacitor 308 primarily initiates the arc inside the flash lamp 313 while aging capacitor 326 is primarily responsible for the spreading or "aging" of the arc throughout the flash lamp 313.

 Xenon arc lamp - Wikipedia, the free encyclopedia
For this reason, xenon arc lamps of smaller sizes, down to 10 watts, are used in optics and in precision illumination for microscopes and other instruments.
In this lamp the glass capsule is small and the arc spans only a few millimetres (hence the name).
Additions of mercury and salts of sodium and scandium improve significantly the lumen output of the lamp, the xenon gas being used only to provide instant light upon the ignition of the lamp.

 Military & Aerospace Electronics - Specialised Imaging introduces short-duration flash lamps that help optimize ...
The SIL 500 Joule flash lamps generate extremely high-intensity illumination for periods as short as two milliseconds that can be easily controlled and precisely synchronized to match the time frame of an event being recorded by a ultra high-speed camera.
SIL 500 Joule flash lamps operate on the principle that electrical energy is stored in large capacitors and then released on command into a specially designed flash tube and in doing so creates a high energy luminous discharge.
Xenon, which is used in the flash tubes, unlike other some gases, produces a spectral output which has energies at virtually all the wavelengths of the visible spectrum making it suitable for both film and solid state sensors.

 Xenon flash lamp shield - Patent 4378583
The flash lamp shield is used with helical xenon flash lamps to shield the radiation from high current density regions adjacent the anode and cathode of the flash lamp.
The inventor has found that it is desirable to use a xenon flash lamp to expose photoresist material, because the light output of such a flash lamp is extremely effective in polymerizing the exposed photoresist.
The invention includes means for permitting light to be transmitted from the helical portion of the flash lamp while blocking the light output from the high current density areas adjacent to the anode and cathode of the flash lamp.

 Micrographia: Flash Photomicrography: The Optics of the Flash Lamp.
That the flash image will be of better quality in terms of evenness of illumination is some compensation -- this is more or less guaranteed by extended size and intrinsically structureless nature of the xenon gas plasma discharge, and the fact that it is imaged only by a single condenser.
The cylindrical coil filament (bottom) is from a Russian microscope lamp and both the looser winding and the depth of the coil pose difficulties in terms of obtaining an evenly illuminated field at the microscope.
It is also important that the glass of the lamp envelope is of uniform thickness and curvature at the end between the filament and the lamp condenser to avoid lensing effects which distort the filament image and result in non-uniformity of illumination at the specimen plane.

In practice, the lamp is left to run at constant current/voltage, and the intensity is modulated using neutral density filters of various kinds.
By contrast, the light from a xenon flash tube has very little heat component, and light-sensitive organisms can be observed and framed at low levels of modelling light intensity -- the flash discharge raises the light level to a photographic intensity only for the moment of exposure.
Xenon flash tubes are more efficient in terms of light output per unit power (Lumens/Joule) than illumination from incandescent tungsten filament lamps.

An oil lamp is a device used for lighting or for preserving a flame that is fueled by animal, vegetable or mineral oil.
In ancient Greece and Rome, lamps were fueled by olive oil; in ancient India, by ghee; in ancient Persia, by petroleum that was found oozing freely from the ground.
Olive oil lamps continued in wide use in countries around the Mediterranean Sea well into the 19th century, with the lamps being mass produced out of metal (most commonly brass or bronze), but otherwise little changed in design from lamps of some 2,000 years earlier.

 Flash Method
The laser flash method, proposed by Parker, Butler, Jenkins, and Abbott of the U.S. Navy Radiological Defense Laboratory in 1960 [1], is the most popular method of measuring the thermal diffusivity of solids.
In this method the front face of a small plane sample (usually disk-shaped) thermally insulated sample is subjected to a very short burst of radiant energy coming from a laser or a xenon flash lamp.
The samples have the shape of the disk with 10 mm in diameter, thickness varies in range 1-5 mm depending on the thermal diffusivity of the measured material.
