The Q-SUN Xe-3 xenon arc chamber reproduces the damage caused by full-spectrum sunlight and rain. In a few days or weeks, the Q-SUN tester can reproduce the damage that occurs over months or years outdoors.

The Q-SUN Xe-3 tester is a full-featured lightfastness, colorfastness, and photostability chamber at a breakthrough price. It utilizes three separate xenon lamps for a large capacity. The Q-SUN Xe-3 tester’s slide out specimen tray is 451mm x 718mm and is useful for exposing large, three-dimensional parts or components. The Xe-3 tester offers standard humidity control, and optional spray, back spray and chiller features.

The Q-SUN Xe-3 is the only xenon arc tester that also has an optional dual spray capability. This allows for a second liquid such as acid rain or soap solutions, to be sprayed onto test specimens.

The Q-SUN Xe-3 is the simplest, most reliable, and easiest to use full-sized xenon arc chamber available.

A More Realistic Xenon
The Q-SUN Xe-3 tester’s xenon arc lamps provide the best match to the full spectrum of sunlight.  Near-horizontal specimen mounting and optional water and back spray provide the most realistic moisture simulation available in a xenon arc tester.  The Xe-3 tester also is the only xenon test chamber to offer a dual spray option, allowing a second liquid (such as acid rain) to be sprayed onto test specimens.  An optional chiller for low temperature applications also allows for simultaneous control of both black panel and chamber air temperature.

Easy To Use
The Q-SUN Xe-3 xenon test chamber is easy to install (proper ventilation required).  It is easy to use and practically maintenance-free.  Specimen mounting and evaluation is fast and easy with the unique slide-out specimen tray.  The Xe-3 tester is completely automated and can operate continuously, 24 hours per day, 7 days per week.  Other features include:

  • Remarkably simple user interface in five user-selectable languages: English, French, Spanish, Italian or German
  • Built-in Ethernet connection for data logging
  • Comprehensive self-diagnostic warnings and service reminders
  • Quick and easy calibration with patented AUTOCAL system
Fast Results

A product exposed outdoors to direct sunlight experiences maximum light intensity for only a few hours each day.  The Q-SUN Xe-3 chamber can subject test specimens to the equivalent of noon summer sunlight for 24 hours a day, every day.  Consequently, specimen degradation can be highly accelerated.
The Q-SUN Xe-3 tester’s low purchase price, low lamp prices and low operating costs create a breakthrough in the price/performance equation.  Now even the smallest lab can afford xenon arc testing.

A Choice of Optical Filters to Simulate a Variety of Environments
Xenon light must be properly filtered to achieve the appropriate spectrum for each particular application.  Differences in spectra may affect both the speed and the type of degradation.  Three categories of filters are available to simulate a variety of service environments, shown below.  The application or test method dictates which filters should be used. 

Daylight Filters
Daylight filters are used to simulate direct, noon summer sunlight.  They provide the best correlation to natural exposures for most applications.  Materials that are typically used outdoors like roofing or exterior coatings should be tested using daylight filters.  Three different types of daylight filters are available for the Q-SUN Xe-3 tester:  Daylight - F, Daylight - Q and Daylight - B/B.

Window Glass Filters
Window glass filters produce spectra equivalent to sunlight coming through window glass.  This spectrum can also simulate other indoor lighting such as the harsh lighting found in a typical commercial or office environment.  Window glass filters are used for indoor materials such as printing materials and textiles.  Four different window glass filters are available for the Q-SUN Xe-3 tester:  Window - Q, Window - B/SL, Window - SF-5 and Window - IR.

Extended UV Filters
Extended UV filters allow excess UV, below the normal cut-on of natural sunlight.  They are used to produce faster or more severe test results.  Extended UV filters are specified in some automotive test methods and are sometimes used for aerospace applications. The most common Q-SUN filter of this type is the Extended UV - Q/B.

The Q-SUN Xe-3 tester’s long-life filters are exceptionally durable and maintain the required spectrum indefinitely.  After many years of use, Q-SUN filters have yet to show any signs of aging.  
Filter Name Nominal Cut-On Recommended Use
Daylight - Q 295 nm Best for correlation with outdoor exposures
Daylight - B/B 290 nm Best for correlation to some rotating-drum style testers
Daylight - F 295 nm Accurate match to the short-wave UV portion of sunlight Used in some ASTM and automotive test standards
Extended UV - Q/B 275 nm Used for some automotive test methods
Extended UV - Quartz 250 nm Very aggressive, very short-wave UV, extraterrestrial spectrum
Window - Q 310 nm Sunlight North American window glass
Meets most ISO & ASTM requirements for Window Glass Filters
Window - B/SL 300 nm Recommended for AATCC procedures like TM 16-3
Meets most ISO & ASTM requirements for Window Glass Filters
Window - IR 320 nm Reduced heat for lower exposure temperatures Recommended for ISO 105 B02 “European Conditions”
Does not meet the requirements for most ISO & ASTM Window Glass Filters
Window - SF5 325 nm Used for some automotive interior tests (e.g. Ford)
