Question About Getting Blue Lasers

jakeGT · Feb 20, 2011

yeah ima bring my lasers to school, and my crack, and my glock! I know I will win show and tell fo sho! haha. but for real. listen to the advice, and what they are saying is pretty blatant. If you are persistant on blue or violet, you will not see the beam with a 405nm (violet) IN THE DAY, with lasers we have on hand today, and 445nm to be able to see pretty well i would say 2 or 300mW and up. and 445, you will only get close to $100 price tag if you build it 110% yourself, cause with 445, a diode is $45.00 wether you want it to output 200mW or 2,000mW. The driver which gives you your "choice" of power, always will be the same price.

You can purchase a pre-set driver with the mAs set at laser threshold- I have one in a mini handheld 3VDC spiro that is <200mWs.(thanks yobresal).

This chart describes it quite well

Lol i always thought blue-ish was the easiest to see. I wonder why the airstrips dont have green lights lining the sides.

ha-HAH!
Well, you see that's not the whole story....
the color response curve is different for daylight conditions or night adapted vision.

Photopic vision in black. (normal light conditions)
Scotopic vision in green. (low light conditions)

The peak is nowhere close to blue light lol. Airstrips should have green lights instead :]

Runway marker lights are color coded. Different colors mean different things, and it's a standardized system. The colors are already most appropriate for their functions and meanings... Trust me, as critical as things like these are, any possible improvements in the color scheme would have been enacted long ago.

Thanks for telling me. Everything is just so blue around here :]

I believe only taxiway edge lights should be blue.

Too lazy to go and check now lol. My friend was there about 3 months ago and said everything was purple..

aryntha · Feb 28, 2011

That's correct. Blue denotes taxiway borders. Active airstrips should not have blue lit borders.

Okay, no more worrying about that topic for me.

Blue are 'end of field' markers or, as stated, taxi-way highlighters. They use Blue to be noticable, but not 'distracting'. Check out the pilot's handbook available as a pdf at the FAA web site.

I guess that solves the problem.
