摘要
激光束直接照射人眼时 ,对人眼角膜和视网膜会造成损伤 ,而焊接光的漫反射光和激光散斑在一定条件下照射到人眼上 ,也会引起人眼角膜和视网膜的损伤。本文根据角膜上辐照度的安全极限 ,导出了激光器光功率与强漫射板上光斑直径。
When the eyes are irradiated directly by laser beams, the cornea and radioscopy will be damaged. Under a given conditions, the diffuse reflection and laser spot in welding can also damage the cornea and radioscopy. According to the safety of the radiant intensity on cornea, the relationship between the power of laser device and the diameter of spot on diffuse reflection board, as well as the distance between the cornea and the diffuse reflection board is obtained.
