Combined environmental testing for finished products and three-dimensional assemblies.
The IWASAKI EYE 4D MULTI Chamber combines selectable light exposure with controlled temperature, humidity, and other environmental conditions, enabling complete products and assembled components to be evaluated under simulated outdoor environments.
The IWASAKI EYE 4D MULTI Chamber is a configurable environmental test system designed to evaluate complete products and three-dimensional assemblies under combined light, temperature, humidity, and other environmental conditions.
Conventional weathering tests often evaluate individual material specimens separately. The EYE 4D MULTI Chamber allows assembled products to be tested in their actual three-dimensional form, helping engineers evaluate environmental effects that can arise from combinations of different materials, components, surfaces, and orientations.
Different light-source configurations allow the system to reproduce ultraviolet exposure, solar-radiation conditions, or infrared heating depending on the application. Environmental loads can then be combined with temperature and humidity control to create more representative product-level reliability tests.
This approach provides an accelerated alternative to relying solely on long-term outdoor exposure when evaluating the environmental reliability of finished products.
Large test spaces allow complete products and three-dimensional assemblies to be evaluated without reducing every component to individual material specimens.
Light exposure can be combined with controlled temperature, humidity, and water-related conditions to reproduce complex environmental loads.
Configurations are available for ultraviolet, infrared, and solar-simulation exposure, allowing the irradiation system to be selected according to the intended test environment.
System configurations support environmental testing from low-temperature conditions through high-temperature exposure for demanding reliability evaluations.
Large-system configurations can support irradiation from overhead and horizontal directions to expose three-dimensional products more realistically.
Water exposure can be incorporated into selected configurations to reproduce environmental conditions beyond temperature and light alone.
Solar-simulation configurations can be designed for test requirements associated with standards such as DIN 75220, MIL-STD-810, and IEC 60068-2-5.
Test-space dimensions, light-source configuration, irradiation direction, and environmental conditions can be selected according to the product and evaluation requirements.
