Comparison of 4 types of laser goggles with video

Comparison of 4 types of laser goggles with video

In this post, we would like to compare and give a small overview about 4 types of different laser goggles.

We are going to set a few experiments

Conclusion

Keep in mind that no goggles give an ultimate protection from a direct laser beam.
The focused laser beam can easily damage any piece of acrylic of glass.
Even if you are more than 1 meter away you still can get pretty high laser radiation if you do not wear goggles.

Laser goggles can protect quite efficiently from an indirect laser beam reflection also if it is not concentrated radiation (not reflected from a mirror or reflective metal).

The laser beam density due to the divergence of the beam decreases in proportion to the area of the light spot, that is, due to the linearity of the divergence (diameter is proportional to distance), it turns out that the density of light (power per unit area) is inversely proportional to the square of the distance with some coefficient.
