The Q-SUN Xe-1 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-1 tester is a tabletop lightfastness, colorfastness, and photostability chamber. It has a single xenon arc lamp and is available with optional water spray and chiller. Its small scale is perfect for a lab with a limited budget or only an occasional need for testing. Installation of the Xe-1 tester is simple and specimens can be conveniently mounted horizontally on its flat specimen tray.

The Q-SUN Xe-1 tester is the simplest, most reliable, and easiest to use xenon arc test chamber available.

A More Realistic Xenon
The Q-SUN Xe-1 tester’s xenon arc lamps provide the best match to the full spectrum of sunlight.  Near-horizontal specimen mounting and optional water spray provide the most realistic moisture simulation available in a compact xenon arc tester.  An optional chiller is available for low temperature applications.
Easy To Use
The Q-SUN Xe-1 xenon test chamber is easy to install - you can exhaust the Xe-1 directly into the room.  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-1 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-1 tester 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-1 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, which are 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 (e.g. roofing and exterior coatings) should be tested using daylight filters.  Three different types of daylight filters are available for the Q-SUN Xe-1 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-1 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-1 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 Application Table
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)
