Understanding UVA UVB UVC Lamp Testing for Accurate Material Aging

1. What are the differences between UVA, UVB, and UVC lamps?

UVA (315–400 nm) simulates sunlight fading, UVB (280–315 nm) accelerates material aging, and UVC (100–280 nm) induces high-energy surface damage. Each wavelength targets different degradation effects.

2. Can light exposure and condensation cycles switch automatically?

Yes. Light exposure and condensation cycles can switch automatically. Users set durations and intervals via the touchscreen for realistic environmental simulation.

3. How is consistent light intensity maintained during testing?

A built-in radiometer monitors UV output continuously. The system adjusts for lamp aging or attenuation to keep intensity within 0.3–20 W/m² throughout testing.
