NettetThe type of LED light used in screens, toys and car lighting contains blue light, and evaluating the risk of blue light damaging the retina requires considering the integrated radiance of the retinal image from the light source (the reflected glow of the light source seen in the eye itself), or the flux of radiant energy per unit area per unit solid angle. Nettet28. mai 2024 · In the diffuse-sky radiance observation, the spectroradiometer provides a featured angular sky scanning, and the sky hemisphere is divided into 354 grids. The measuring probe can rotate in two orthogonal dimensions of pitch and level, so as to obtain the absolute integrated radiance in the whole sky.
