Figure S1: Photographs and schematic diagram of the optical setup from Key functional role of the opticl properties of coral skeletons in coral ecology and evolution

Photographs and schematic diagram of the optical setup employed for the estimation of the light enhancement factor (LEF) across different naked coral skeletons of Scleractinian corals. (1) Laser; (2) Lens to couple the laser beam to the optical fibre ; (3) Optical fibre; (4) Isotropic source of light; (5) optical fibre support; (6) coral skeleton; (7) collection lens with mount; (8) light detector.;Mean ± STD of the light enhancement factor (LEF) determined for the 74 species analysed.
