p.1 #1 · p.1 #1 · Beware of Lasers at functions


I have been at a number of functions where lasers have been part of the show and never fully appreciated that they could cause irreparable damage to camera sensors. My understanding is the lasers were not of sufficient strength to cause damage, but I was wrong.

I had read this from DPReview from someone who had just damaged their new D850 at a NYC disco.

Blue and green are supposed to be the worst even at levels as low as 50mw.

Iím a laser enthusiast, the color doesnít determine the power, they are all equal. The green looks the most powerful because of itís wavelength. Our eyes have a peak sensitivity around 500nm, the green part of the spectrum. A 1 watt red laser will burn as bad as green, however, if the laser ( no matter the color ) hits its complementary color, then that laser will burn faster as the radiation will build up faster. So if a red laser hits a red color, it will take long to burn, if green hits red, look out! If any hit black surface, the energy will be absorbed and they all burn quickly that way. They all will damage the eyes though.

If you are far enough away, the beam spreads out vastly, could be foot wide, itís just bright, no heat. But your camera lens can refocus and concentrate the light again and it will burn.

And to think of the 50W laser cutter in our shop!

Eclipses have some problems too:
