what sort of distance should one expect out of a 100 mw blu ray in an aixis module?

I'm sorry. What do you mean by "what sort of distance . . ."?

Peace,

As far as you can see it.... it will probably carry farther then your eye can see.

There is a warehouse about 1.5 miles from my house, across the valley. With my friends spotting scope(at night), I could easily see the dot from my bluray on the side of it. I am running an 803t @ 150mA.

It's not the best thing for pointing though. Like I said, I can barely see it 500m away in the night because my eyes have a hard time focusing on it.

I guess it because the diffraction index of your lens at 405nm is so different than most ambient light it's totally unfocused on the retina and looks like a blurry blob rather than a dot.Or if you focus on the dot , everything else looks blurry. :-/

Very true. I should have added that to my post, since the absolute ONLY way I could see/ try to focus the dot at that distance was to use the scope. Without it, the dot becomes invisible at about 1/4 mile away. The only way I can focus at distnces where I can still see the dot by eye is to make the "blob" as sharp as possible(kindof like using the sharpness control on a TV).
