The SN xenon lamp test chamber can be used for selecting new materials, improving existing materials, or evaluating changes in durability after changes in material composition. It can simulate the changes in material exposure to sunlight under different environmental conditions very well.

Simulate full sunlight spectrum

SN measures the light resistance of materials by exposing them to ultraviolet (UV), visible light, and infrared light. It uses a filtered xenon arc lamp to generate a full spectrum of sunlight with maximum consistency with sunlight. The xenon arc lamp with reasonable filtering treatment is the best way to test the sensitivity of products to longer wavelength ultraviolet and visible light in direct sunlight or sunlight passing through glass.

Light resistance test of indoor materials

Due to long-term exposure to fluorescent lamps, halogen lamps, or other luminescent lamps, products placed in retail points, warehouses, or other environments will also undergo significant photodegradation. The SN xenon lamp test chamber can simulate and reproduce destructive light in such commercial lighting environments, and can accelerate the testing process with higher intensity.

Simulate climate environment

In addition to conducting photodegradation tests, the SN xenon lamp test chamber can also become a climate aging test chamber by adding a water spray option to simulate the impact of outdoor moisture on materials.

Relative humidity control

Some models of SN xenon lamp test chambers can provide relative humidity control function, which is also important for many humidity sensitive materials, and many testing protocols require humidity control.
