激光分类 激光分类说明
I 激光辐射不被视为危险的激光产品。
IIa 1,000 秒以下的观察不被视为危险，但超过 1,000 秒的慢性光束内观察被视为危险激光产品。
可应用于波长为400~710nm的可见带激光器。
II 慢性光束内观察被认为是危险的激光产品。
可应用于波长为400~710nm的可见带激光器。
II Ia 由于辐照度的程度，慢性光束内观察和临时光束内观察都被视为危险的激光产品。
此外，在光学仪器中直接观察光束是危险的，即使很短的时间。可应用于波长为400~710nm的可见带激光器。
IIIb 即使很短的时间，直接暴露在皮肤和眼睛被认为是危险的激光产品。
IV 不仅直接暴露在皮肤和眼睛上，而且短暂暴露于散射光中也是危险的激光产品。
