Sincerely investigate any of these three short quotes as new concepts and you've taken your first step into a larger world:

"I regard consciousness as fundamental. I regard matter as derivative from consciousness..." - Max Planck. "Everything we call real is made of things that cannot be regarded as real" - Neils Bohr. "What we call physical things and events do not exist independently of subjective experience..." - Deepak Chopra.

Each of these three rabbit holes go deep, ending up in the same place.

OK, so if you replaced the tube in your desktop cutter and clamped the tube down in the little strap holders, then these screws in the metal head could let the user align the beam Left, Right, Up, Down so that it aligns in their machine.

That is the OC mirror is still parallel with the rear mirror and these screws don't adjust the OC In, or Out, nor are they meant to adjust the tilt or parallel alignment with the rear mirror, they just set the beam exit in the OC's center for alignment purposes so the beam strikes the machines internal mirrors as the old tube did.

I think I would rather have a tube that has been factory aligned and centered, not that these aren't, but as I don't want to move the OC at all, there is no benefit in my paying extra for this feature, thanks for the info gentlemen.

-----EDIT-----

Apparently I must spread some rep around before I can acknowledge all the helpful info, so for now Thanks

-----EDIT-----


Looks like China has a couple competitors, let's see these get down to what they should be, if you can get an NUBM06 with the good GBall you can put on a 3X BE from sanwu and it will work really well with the GBall intact.

If you adjusted the OC the laser would stop lasing...

Hi, the four screws are used to adjust the laser path and spot size when manufacuring. Most time you do not need to adjust it. We set it as best performance before shipping.

That was my gut feeling as well Alaskan, better to not adjust it, I just wanted to see what anyone might know in case there was an advantage of some sort.

Thanks for the research.

Also be careful to read about the beam specs before buying.

I don't think this is an expander, just a 532nm laser pointer of unknown power with a focusing lens on the output. For the price, I wouldn't get one.

I like the looks of it but no power specs turns me away. Maybe if the price were 39.95 I'd take a chance.

Sincerely investigate any of these three short quotes as new concepts and you've taken your first step into a larger world:

"I regard consciousness as fundamental. I regard matter as derivative from consciousness..." - Max Planck. "Everything we call real is made of things that cannot be regarded as real" - Neils Bohr. "What we call physical things and events do not exist independently of subjective experience..." - Deepak Chopra.

Each of these three rabbit holes go deep, ending up in the same place.

Useless troll fighting.

TechHood has had these for a long time, his 445 is a 2w model though.

Focusable 10X Red 100mW 532nm Green Laser Beam Expander/Scope Light Supplement | eBay


HIS 445 is listed as a 2 watt.

-------EDIT-------
I am so tempted to buy these But I just got burned on that linos, some modifications would be needed but overall I think we may could get some use from some of them.

The "Red" in the title must be just a bit of "Chinglish" I guess?

If someone wants to get these I may be willing to take one off your hands - I'd get both if the shipping wasn't so expensive to get to me, shipping is ~50% of the "Buy It Now" price for me.
