The STD SOLARBOX 1500 – 3000 is a series of xenon arc weathering test chambers manufactured by Cofomegra, Italy. It is primarily used to simulate natural sunlight and conduct accelerated lightfastness and weathering aging tests on materials, products, or samples.
This equipment simulates the solar spectrum (including ultraviolet, visible, and infrared radiation) through a xenon arc lamp and combines precisely controlled environmental parameters such as temperature, humidity, and irradiance to evaluate the color stability, mechanical property changes, and aging degree of materials under long-term sunlight exposure.
Working Principle
The STD SOLARBOX 1500–3000 is mainly used to simulate natural sunlight and perform accelerated aging tests on materials such as coatings, textiles, plastics, and other products.
Its core working principles are as follows:
Xenon Arc Lamp Sunlight Simulation
The system uses a high-performance air-cooled xenon arc lamp (for example, the Solarbox 3000e uses a 2500 W lamp).
The emitted spectrum closely matches natural sunlight and can generate radiation intensity equivalent to approximately twice the natural solar irradiance (e.g., 1100 W/m²).
Closed-Loop Radiation Control System
A built-in sensor continuously monitors radiation energy and automatically adjusts the xenon lamp power to compensate for intensity reduction caused by lamp aging or filter degradation, ensuring constant irradiance and improving test repeatability and accuracy.
Environmental Condition Simulation
The system can simulate real environmental conditions through the following functions:
Optional humidification system to simulate dew or rainfall
BST (Black Standard Temperature) sensor for accurate sample surface temperature control
Programmable light/dark cycles
Optional spray/no-spray programs to simulate day–night and weather changes
Optical Filtering System
Standard optical filters (e.g., 290 nm cut-on filter) optimize spectral output to better replicate the ultraviolet composition of real sunlight, enhancing the realism of aging tests.
Uniform Irradiance Design
A specially designed curved stainless-steel reflector evenly distributes light across the sample tray, preventing localized overexposure.
