Product Description

xenon quartz flash tubes
Xenon Flashlamps

Xenon flashlamps generate high-intensity light pulses by instantaneously discharging the energy stored in a capacitor. In addition to producing high-intensity light instantaneously, they can flash repeatedly at high speed. These lamps offer continuous spectral characteristics ranging from ultraviolet to infrared to provide artificial light closest to natural sunlight. Users can also adjust the output spectrum by switching the window material or adding optical filters.
Visible light is used for still photography and video imaging, as well as for other applications including aircraft warning lights.
Infrared light is used as a light source for infrared cameras and as a heat source.
Ultraviolet light is used as a light source in medical and analytical equipment and for illuminating fluorescent paint.

Shortwave infrared lamps utilize a low-quality tungsten filament to provide a high temperature source that responds quickly to voltage changes for precise control in your industrial infrared heating process. These quartz infrared lamps are sealed and filled with an inert halogen gas, which helps extend the life of the filament. Shortwave IR emitters feature a white ceramic or gold reflector coating on the back of the lamp to make it unidirectional. Glare-free, ruby red, Helen gold-coated, and satin-coated quartz lamps are available to filter out most high-intensity visible light.The sealing area at both ends of the shortwave infrared lamp consists of a flat molybdenum ribbon welded to the tungsten filament and lamp holder leads or other terminations and clamped to be airtight. Several ceramic and metal bottom covers are available as below:


Quartz glasses Quartz glass gains its unique resistance to arc and thermal shock from the high bonding energy of pure SiO2 and the negligible small expansion of 4 x 10-7/K. Quartz glass usually requires manual processing.
Quartz glass Q1:
• UV transparent.
Quartz glass Q2:
• Reduced generation of ozone. Quartz glass Q3:
• No generation of ozone.
Quartz glass Q1, Q2 and Q3 differs mainly in their UV transparency. Synthetic
quartz glass is available on request. wavelength (nm) thickness 1mm

Color corrective coatings and colored lamps Hard glass and quartz glass can be coated with a yellow layer that absorbs the excessive blue radiation for film exposure. The color temperature is lowered by 1000 to 2000 K. For special applications, flashtubes can be colored with uniform and crack-free colored layers. Typical colors are red, blue, amber, green, and purple.

Life expectancy Flashtubes age in terms of light output reduction and decreased ability to trigger the lamp. Statements on the life of a specific flashtube require exact knowledge of the following operating conditions: • flash energy, • anode voltage, • flash frequency, • flash capacitor and its effective series resistance, • resistors and inductances in the discharge circuit, • reflector, • cooling conditions, • criteria defining the end of life. All details of the life expectancy mentioned in the catalog refer to nominal operating conditions that are described in the individual specifications. The flashtube drawings shown on the following pages are schematic sketches only. Further details, as well as tolerances of the mechanical dimensions, are provided in our data sheets, available on request.
