Solar Light's precision research-grade 16S-150-001 SPF Testing Solar Simulator is specifically designed for In Vivo SPF sunscreen testing in compliance to the latest ISO24442, ISO24444, FDA Final Rule, JCIA, Australian, and COLIPA spectral irradiance standards. This state of the art single output 150W unit produces solar UV radiation in the 290-400nm range, and can be quickly and easily configured by the user to provide UVA only, UVB only, UVA+B, or full spectrum sunlight optionally. The unit's 0.4" / 1 cm horizontal beam output is approximately 20 times the intensity of the sun, delivering 2.9 MED/min UVA+B or 85 mW/cm² UVA-Only. A patient stop is included as shown to ensure accurate irradiation onto the test subjects. Our DCS-2 Automatic Dose Control System is also included to continuously monitor the output, and automatically deliver the exact required dose. Everything required for instant testing right out of the crate is included direct from the factory: Solar Simulator, Automatic Dose Controller, NIST-traceable SUV and UVA Sensors, and all related accessories.
