1.5.3 Laser Device Classifications
Laser devices of class 1M, class 2, class 2M and class 3R
Precautionary measures are only necessary to avoid a permanent direct looking into the laser beam; for classes 2 and 2M is a momentary (0.25 sec.) irradiation in a wave length range between 400 nm and 700 nm, as it may occur when you accidentally look into the beam, not considered to be dangerous. However, you should not level the laser beam intentionally at people. The use of optical aids (e.g. binoculars) together with laser devices of the classes 1M, class 2M and class 3R may increase the danger for the eyes
