what is the harm of laser to the human body
According to the laser diode manufacturer, when the laser laser beam reaches the sensitive part of the retina, it can cause damage to the eyes.In addition, after a long sight of dazzling light, it can also affect the optic nerve and the central nervous system, causing dizziness and even nausea.Therefore, laser beams should not be used to illuminate other people's faces or eyes, nor to reflect the laser with objects such as mirrors.What are the dangers of laser light?
Primary standard of laser, the output power to be less than 0.4, this is because the energy of laser to eyes and skin in any case, will not cause damage, even after focusing through the optical system will not cause harm to human body, so this kind of laser products without special management type.
The laser output power of the secondary standard is between 0.4mw and 1 milliwatt. The reaction time of the person closing the eye is 0.25 seconds, and the amount of exposure can not exceed the MPE value in this period.Usually a laser with less than one milliwatt can cause a person to have a vertigo, so you can't use such a laser to directly illuminate your eyes, and you can't see the laser with a long-looking device.
A three-level laser beam directly into the eye can cause damage to the eye, and its output power is between 1 and 500 milliwatts.
The four-level standard laser is a high output continuous laser with a power output greater than 500 milliwatts, which can be dangerous to fire.
