Abstract
A system and method for testing an effect of light exposure on a skin sample include a solar simulator arranged to administer a combination of visible light (VL) and long wavelength ultraviolet radiation (UVA1) to the skin sample. The solar simulator includes a lamp for generating a light beam and at least one customized filter for receiving the light beam and emitting a VL+UVA1 spectral output having a wavelength range of 370-700 nm for irradiating the skin sample.

A system for testing an effect of light exposure on a skin sample, the system comprising:
- a solar simulator arranged to administer a combination of visible light (VL) and long wavelength ultraviolet radiation (UVA1) to the skin sample, the solar simulator including
- a light source for generating a light beam;
- and
- a filter combination including an interference filter for receiving the light beam and emitting a VL+UVA1 spectral output having a wavelength range of 370-700 nm with 2.0%-5% UVA1 (370-400 nm) for irradiating the skin sample.
