(Reference) Overview of Laser Safety Classes

Wavelength of the laser: 400nm to 700nm Same as Class 2, but potentially

hazardous when optical instruments are used.

Class2M

Wavelength of the laser: 302.5nm to 4,000nm Same as Class 1, but potentially

hazardous when optical instruments are used.

Class1M

Diffuse reflection may be hazardous.Hazardous to eye and skin, so protect them.

Fire hazard.

Hazardous when eye is exposed, but diffuse reflections are usually safe.

Wavelength of the laser: 302.5nm to 10

nm Potentially hazardous when eye is

exposed.

Wavelength of the laser: 400nm to 700nm Safe for unintended exposure, but

prolonged staring should be avoided. Naked eye is protected by blink reflex.

Safe for normal operations, and not hazardous when optical instruments are

used.

Explanation

• As for the [Class1M], it does not cause physical harm unless you do not see LED beam directly

using lens or optical instruments.
