The Berger Solar Simulator is designed to test light-sensitive patients for their sensitivity to ultraviolet light. The present modification was performed to make testing with UV and visible light possible. The modification consists in replacing the dicroic mirror with a beam splitter (BSP 580) and the filters with a WG 340 allowing 340-565 nm to pass. Subdivision of that spectrum is performed by inserting a Wratten 12 (500-565 nm) or a Wratten 2B (400-565 nm). Infrared is excluded by a KG3 filter.
