Would be nice if we didn't need to block a whole colour , just two or three wavelengths.That probably wouldn't affect white light much....pullbangdead said:^Well, filtering one color of light can't really easily result in white light coming out the other side. The colors you often see with glasses are the result of the absorption of a color. Absorb all the green, and you'll get red. This is simply from the color wheel of opposite colors, green is opposite of red. This isn't a hard-fast rule, but you generally can't block a color without screwing up other colors too, and you certainly can't still get white from outside the plane through the cockpit. The mesh you're talking about might be a Faraday cage, which is a screen of a conductor where the holes are significantly smaller than the wavelength of the electromagnetic radiation. We use them around RF sources in a lab I work in. This means to block visible light, the holes are on the nanometer scale, which is doable, but it certainly isn't selective, it blocks all above it and none below it, as you observed with it stopping red and allowing violet to pass. This wouldn't really be feasible either since if it's blocking light, it's not transparent anymore, and won't make a very good window.
Also, look at airports at night. They use almost all colors of lights for indicators on the ground, including red, blue, green, yellow, and white. You can't block these colors, because the pilots need the indicators when operating the planes on the ground and when landing and taking off.
Basically, it's just like anything else, people need to be educated and not do stupid things with lasers. People can do stupid things in a car, people can do stupid things with guns, and people can do stupid things with lasers. Any of these can hurt others, it's up to education and responsible decision-making to stop idiots from messing things up for everyone els.
