Fig. 10: Thermal simulations at the iris plane.

a Temperature increase in the modelled eye after 150 s of continuous illumination on the iris at the MPE (565 nm, 15.25 mW mm⁻²). b Quantification of the temperature increases at the iris plane during 150 s of continuous illumination for increasing irradiance levels from 1.25 to 15.25 mW mm⁻² (increments of 1 mW mm⁻²). c Quantification of the time to reach a thermal increase of 2 °C (left axis) as a function of the irradiance at the iris plane for continuous illumination at 565 nm (black circles and line). The coloured lines show the irradiance obtained at the retinal level (right axis) for ten pulses repeated at 5 Hz (red line), 10 Hz (blue line) and 20 Hz (green line) as a function of the irradiance at the iris plane for continuous illumination.
