Light causes product damage resulting in losses totaling vast amounts of money each year. Products or materials exposed to direct sunlight, or to sunlight filtered through window glass, are subject to maximum risk.

The Q-Sun Xenon Test Chamber uses full spectrum xenon arc lamps to reproduce the damaging wavelengths of light encountered in a multitude of environments.

Q-Sun is used for the selection of new materials, the improvement of existing materials or evaluating the changes in product formulation that affect product durability. This is an ideal instrument for total Accelerated Light Stability and Weathering Testing; and can be used to test for light stability quickly.

Full Spectrum Sunlight Simulation

The Q-SUN tests materials for Photostability by exposing them to UV, visible and IR light. It uses filtered xenon arc light for the ultimate correlation to the full spectrum of sunlight. Depending on the desired effect, the xenon light is normally filtered to achieve an appropriate spectrum like direct Daylight or sunlight behind Window-Glass. The exposure application or test protocol dictates which filters should be used.

Weathering

The Q-SUN Xenon Test Chamber can be operated as a weathering tester by the addition of the Water Spray Option to simulate the effect of moisture on materials exposed outdoors. The spray periods are completely programmable and can be timed to occur during either the light or dark periods. In addition to the moisture effects themselves, the Q-SUN's water spray cycle is useful for introducing thermal shock and mechanical erosion.

The spray times on the samples are not dependent on the exposure of a moving sample to a stationary spray, but are based on the programme and can be set to suit the test, since the samples are stationary.

Indoor Photostability Testing

Products exposed to fluorescent, halogen or other general lighting lamps in retail, warehouse or other environments, may also experience significant photodegradation.

The Q-SUN's low purchase price and low lamp prices are a breakthrough in the price/performance equation. Both the economical bench-top Q-Sun Xe-1 and the larger Q-Sun Xe-3 testers offer the features needed in a xenon arc chamber:

• Full Spectrum Xenon Light
• Choice of Filter Systems
• Solar Eye TM Irradiance Control
• ISO 9000 Calibration
• Black Panel Temperature Control
• ISO and ASTM Compliance
• 3D Specimen Mounting
• Water Spray Option
• Humidity Control Option
• Easy to use
• Available in free standing & desktop models

Simple to Use

The Q-SUN Xenon Test Chamber is easy to install, easy to use and practically maintenance free. Specimen Mounting is flexible, fast and easy with the Q-Sun's unique slide-out specimen tray, accommodating different sizes of flat panels, as well as three-dimensional components, parts, bottles, test tubes or Petri dishes. Low cost air-cooled lamps are very quick and easy to replace, while long-life filters maintain the required spectrum. The Q-SUN is completely automated and can operate continuously, 24 hours a day, 7 days a week.
