Green Lasers

[TMan]

Has anyone tried or at least looked at the green lasers that are now available? They seem to be a bit higher in price. I'm wondering if it is worth it.

For absolutely no good reason at all, I picked up a green laser on eBay a couple of years ago. Nothing you'd bolt on a firearm, just a pen style laser pointer. It is dramatically easier to see, especially at dusk, where you can often see the beam as well as the point. I'll have to dig it out and see how my laser capturing picture skills measure up.

Interestingly enough the red vs. green issue is one that has plagued engineers for years. Due to the wavelength and frequency of red light it is ill suited for areas having restricted visibility (ie. smoke, fog, rain). It cannot be seen at the same distance a green light can. If traffic engineers could do it all over again they would reverse the role of red lights vs. green lights. For sure green can be seen in smoke much better than white or red. The same is true for lasers.

hmmm... green light districts.

red lights are often used in low light situations when people will be going in/out of darkness and want to preserve their night vision. Red does not affect your night vision as much as traditional white light. That doesn't really apply to laser question...but a little tidbit.

I don't have research, but from personal experience, the green is a bit easier to see with my colorblind eyes. I hate trying to track down the lasers during presentations. Too many presenters don't know how to use them and move them around too much and too fast.

The has been some changes in the red light controversy. Modern boats now use blue/white lighting on the instrument panels for night vision instead of the customary red.
