So, I have a good question :)

I was thinking about buying a beam expander for my Arctic like the 10X one from their site. I'm excited to see this sucker with a gigantic, fat, beam. Especially in the winter hitting the snowflakes. And when thinning it out I know it's more sharp and can travel longer, but I'm curious if when I use it to thin out the diameter of the beam, will the focusing effect make the beam brighter because of the greater density of light per area of the beam?

Thoughts?

Hello MacDaddy.

The expander if I remember correctly will in fact make the beam go farther and will keep the beam brighter for longer distances.

For example:

Without Expander: --=Visible Beam ~~~=Non Visible Beam
Normal Artic: ----------------~~~~
W/ Expander: --------------------------------~~~~

Hope I helped.

What do you mean by "thin out the diameter of the beam"?

Beam expanders, as the name implies, will expand the laser beam. This will lower the divergence at the cost of beam diameter, in effect you will get a smaller dot over long distances than without the expander.



What's up with the "non-visible beam"?
