How Far Can You See A Green Laser In Daylight

The photos were taken with the lasers about 10 feet from the target.

How far can you see a green laser in daylight. One only needs three rather simple equations for all the calculations done in this article. Inside science have you ever played with a pocket sized laser wondering how far its light would travel. I sighted it in for 50 yds which worked fine in daylight. Similarly the bottom two bars show that the green laser has much longer visual interference distances than the blue laser even though they both are the same power and thus have the same nohd distance.

At night it was visible way further than i could accurately hit. In the low light photo you can see some speckling in the green dot which occurs when the laser s lens gets dirty. That s closer than i shot the drills but my camera can t see the laser as well as a human so the lasers had to be moved in for the pictures. So yes you can technically use any laser distance measure outside but depending on the distance you want to measure they may do what you want them to do.

Could you a naughty student inside a classroom on earth annoy a poor substitute teacher on mars by waggling your laser pointer at him. Outside in full sun you will not be able to see the laser dot more than about 10 or so meters 30 feet. The 1 mw red pointer has a glare distance of 255 feet compared to the same power green laser which can cause glare at 490 feet. I put a green laser on an ak too.

It was visible just barely at 100 yds in broad daylight.
