求翻译：9、不要直视或通过光学仪器直视从光纤输出端传出的光束，激光光束对眼睛有直接的伤害，从光纤输出端输出的激光标称眼伤害距离（NOHD）为1m。是什么意思？

9 Do not stare or look directly at the beam emanating from the fiber output through optical instruments, the laser beam on the eye has a direct injury, eye injury from the (nohd) for 1m from the optical output of the laser output nominal.

9, do not stare directly into or through the optical fiber equipment look from the output end of the beam, the laser beam to the eyes of the injury, there is a direct output from the fiber output of the laser eye injury that distance (NOHD) is 1 m.

9, do not open or open through optical instruments outgoing from the fiber output side of the beam, the laser beam has a direct harm to your eyes, from nominal output fiber output laser eye hurting distance (NOHD) is 1M.

9th, do not have to look straight ahead or through optical instrument looking straight ahead the light beam which spreads from the optical fiber out-port, the laser light beam has the direct injury to the eye, outputs the laser nominal eye injury from the optical fiber out-port to be away from (NOHD
