Functional characteristics of green laser pointer:
The wavelength of the light emitted from the green laser pointer is 532 nm, which belongs to Class IIIA. The light of the green laser pointer is a little objective and dangerous to the eyes. The higher the output power, the more dangerous it is. Normally, 5mw works well, the US market accepts 5mw laser pointers, but above 5mw, special approval is required. Please be careful when using it. Please do not shoot it at the eyes or in a place where it is easily injured. And you should also prevent the laser light from getting into your eyes due to reflection.

Laser principle-purple laser pointer
A blue-violet laser diode with a wavelength of 405 nm is used. It belongs to a semiconductor 1000mw laser pointer. It is close to the ultraviolet wavelength band and has low visibility, but it can excite fluorescence and has functions for currency detection and chemical inspection.

Due to the cause of Rayleigh scattering of air molecules, low power green light can be seen even at night. Such Rechargeable Laser Pointer are often used by astronomical enthusiasts to shoot stars and constellations.
The green laser pointer 1mw is the safest and can be seen even in the dark.The human eye is more sensitive to green light than red light.
Green light scatters more in the air than red light.
