Hey TJ, do you think a different collimating lens would make any difference in divergence? I have one from one of the 405nm pens that I took apart for "science" and if it would improve it I'm all for it.

I'm not a pro when it comes to optics. In fact I'm not a pro on most laser related operations. I've just read a lot the 3 years I've been here.

You could always try, but the coating is not the same.

I like the torch form factor because they have the push button tailcaps and fit in the hand a little more comfortably. It also seems to me that because they are larger and beefier that they will hold up a little better. This could all be in my head but that's how I look at it.

YMMV

Just point it at the furthest thing possible you can see, and focus it to its tightest beam.

If I understand focusing, it's really a matter of where the smallest , most focused beam is for burning but with something like this if you set it to further away it just results in a little wider beam at the aperture. Not all that noticeable.

BUT this is my understanding. I could be talking out my a$$

but then won't it be unfocused at close things?

That's why they are focusable, so you can focus them close for burning, or at a distance for pointing. You can't have both unless you use an external lens. If you don't want to have to focus it every time, focus it once and put a drop of glue on the lens thread. Done.

I have done well ordering from lasersman.com. I have developed a close relation ship with a staffer there named Kath. If you want to place and order from there be sure to contact her first. Try this coupon code HZLMlaserpointer for 10% off and free shipping. It is the cheapest legitimate site I could find. I have ordered 4 times from lasersman and the shipping is a bit slow but I am happy with the service. Kath also has a facebook page to reach her on. Kath Smart | Facebook

So after some contact with the seller they are going to send me a replacement module that is focusable in the hope that itll be better than this one. Ill update when its received.
