The xenon lamp test box uses a xenon arc lamp that can simulate the full sunlight spectrum to reproduce the destructive light waves existing in different environments, and can provide corresponding environmental simulation and accelerated tests for scientific research, product development and quality control.
The xenon lamp test chamber can be used for tests such as the selection of new materials, the improvement of existing materials, or the evaluation of changes in durability after changes in the composition of materials. It can well simulate the changes in materials exposed to sunlight under different environmental conditions.
Simulate full sunlight spectrum
The optical resistance of the material is measured by exposing the material to ultraviolet (UV), visible light and infrared light. It uses a filtered xenon arc lamp to produce a full sunlight spectrum with the greatest consistency with sunlight. The xenon arc lamp with reasonable filtering treatment is the best way to test the product's sensitivity to longer wavelength ultraviolet and visible light in direct light or sunlight through glass.
Optical resistance test of indoor materials
Due to long-term exposure to fluorescent lamps, halogen lamps or other light-emitting lamps, products placed in retail outlets, warehouses or other environments will also experience significant photodegradation. The SN xenon lamp test chamber can simulate and reproduce the destructive light in such commercial lighting environment, and can accelerate the test process with higher intensity.
Simulated climate environment
In addition to the photodegradation test, the SN xenon lamp test box can also become a weathering test box by adding a water spray option to simulate the influence of outdoor moisture on materials.
