You keep telling yourself that ::)

Well you shoud've indicated that.Someone who has no knowledge of the companies out there couldn't have told. :-/

Your eyes hurt because of the green , not because of the IR. You should be more concerned about the green , it's can cause a lot more damage than the IR. ::) Besides, most green protection goggles are just for the green, that's why people buy them.IR goggles are more expensive.

If you blew 5 out of 5 you must be doing something wrong.Very small chance that you were that unlucky :-/

Amen to that ::) I don't even know who some of you were :-/ It's like when you change your name , you change your identity.People don't remeber who you are, what you did , what you built and what you posted.The avatar has a pretty important role too, especially for people with hard to read...

A beam expander is what you want. :P It will increase the diameter of the beam , decreasing divergence, which is not a bad thing unless you purposely want it to have worse divergence.

What does that have to do with laser being weapons? It's clear that laser weapons fall in the directed energy weapons category and not in the kinetic weapons category, that use sharp and heavy stuff that fly at very high speeds :-/

besides, 1.4mW is not gonna be one helluve glow ::) You mean from near IR to "nearly" UV :D

Yea, that;s andy's video and his DIY glove not the playzerz glove.It was for sale a while back for a lot less than $139 , those prices are ridiculous ::) You can make one with less money with lasers included. :P The red lasers price is about right if they have a driver and everything, but $44...

I was gonna comment about his sig but was thinking it's offtopic.I guess you didn't :P Anyway, the speckle pattern was one of the many things that made me consider my first 1-2mW red laser pointer as the coolest thing I've ever seen about 10 years ago.It was a complete mistery to me. ;D

I don't know how they make wine glasses but in the technical sense, "glass" and "crystal" are opposites. :P I have no idea what "crystal-glass" can mean, it makes as much sense to me as a round square. ;D

That's completely imposible if the optic is placed at an angle.Maybe one laser shining into the other if you set it up wrong.

You are forgeting that the wide beam is actually more beams.The beams are collimated before the concave mirror, then they are spreaded by the mirror, then they are collimated again by the big concave lens, reflected back into the lens, spreaded out by the lens, collimated by the concave mirror...

I'm afraid 1AA isn't gonna be enough voltage even with the flexdrive.You might wanna use an AA sized lithium battery. :-/

First year at a university (but should be 2nd year if I haven't took a year off out of lazyness).

I never thought BOB ;D Btw wes, you have a pretty common wavelength at 671 coming up ::)

No, a mole has N atoms/molecules(where N is Avogadro's constant) but it doesn't have N grams or N a.m.u.The mole is a measure of physical quantity not mass. The mass of a mole depends on the substance ::) So both of you are retarded (kidding ;D lol, but if I'm wrong I'm really retarded :D)

What your friend probably meant is that by optical standards , acrylic is cr@p and would not normaly be used for this.The answer you should've given him is "because it's really cheap, available, and not coated as opposed to the cheap and available glass lens that is coated for the other side of...

I don't get it...You don't want to have an exiting beam? :-/ Theoretically , the mirror could replace the first concave lens.If you would have a hole where the flat mirror is , then you'd have an exiting beam (an big ugly beam that would actually be lots of parallel beams).If you have a flat...

Makes perfect sense that the answer to life, the universe and everything divided by pi is 13.37 :D Btw, I don't get the 2.9999999/3 thing :-/
