Demand for products to survive prolonged outdoor exposure continues to expand. With the phenomenal performance of the EYE SUPER UV TESTER from EYE Applied Optix™, you can get faster and more accurate exposure testing, making it an indispensable tool for material development and research.
How the Super UV Test Chamber Works
The EYE Super UV Tester uses a proprietary high output UV lamp that generates ultraviolet light very efficiently. Its UV irradiation intensity is 30 or more times greater than that of sunlight and conventional weatherometers. For even greater solar correlation, UV radiation below 295 nm is removed from the light source by a custom filter. Removing this radiation below 295 nm – that in natural sunlight does not reach earth – produces an acceleration in deterioration that more closely resembles outdoor exposure. There is no risk that light of a wavelength not present in sunlight will bias the test results.
METAL HALIDE LAMP
The proprietary metal halide lamp used in the SUV-161 generates a high level of UV that is then reflected onto the test surface inside the chamber with a specially designed reflector. The resulting spectrum of the Super UV Test Chamber is seen in purple below. In this spectral chart, one can see the difference in UV output from the Super UV versus other test units and natural sunlight.
“The Super UV provides highly accelerated data compared to xenon and fluorescent tools. We’re able to rapidly screen formulations, increase test throughput, and correlate to outdoor and traditional test methods.”
– Mark Alessandro, Global R&D Durability Manager, Avery Dennison
Benefits and Features
- Compresses years of detrimental UV radiation effects into just weeks of testing, allowing rapid verification of designs and significantly shortening product development time.
- Ensure optimal test correlation with natural UV degradation.
- Reliable long duration test results, even as the lamp ages.
- Increased test productivity utilizing saved tests for repeatable test results.
- Promptly review data with the built-in data logger.
- Improve customer satisfaction and reduce warranty costs by discovering product design problems and marginal components to be corrected during product development.
- Highly Accelerated Life Testing (HALT)
Our proprietary metal halide based high-output UV lamp delivers 10 times the acceleration of typical weathering chambers, dramatically shortening life cycle testing.
- Correlated Acceleration
The SUV-W161 system can generate 30 times natural sunlight UV energy (UVA/UVB) to provide acceleration factors greater than 100, correlated to outdoor exposure
- Natural Sunlight Replication
The fully integrated, proprietary lamp provides UV, while the spectral filter system cuts UV irradiation below 295nm to block the harmful UV not found in surface sunlight.
- Automated Irradiation Control
The desired UV irradiation intensity is easily set on the touch panel and then controlled by an electronic feedback system.
- Simple Data Capture and Analysis
The SUV-W161 system includes a built in data-logger for data storage and simple transfer to common programs such as MS-Excel.
- Flexible Test Setup
All weathering parameters and cycle functions are fully programmable including temperature, humidity, rainfall, UV power, rest (night time), and cycle/duration timing. All functions are easily saved for quick recall to ensure repeatable test results and increased test productivity.
