I can barely feel my 30mW on my skin but that's just because I got a bit of a tan. :D

What do you guys mean blue , violet and purple? Purple is the color you get by mixing red and blue. It isn't a spectral color (it cannot be found in the rainbow and it doesn't have its own wavelength).So purple isn't monochromatic. Blu-rays are violet, blue DPSS is blue (doh) and in between...

Wow that is a significant improvement indeed! I see you already sold one at only a day after the post. I'm sure they'll sell fast.

Yea I know, but chipdouglas was refering to the wavelength since he compared 1nm with gamma-rays and x-rays.I know he didn't get what you wanted to say, I just wanted to answer his question , even though it was a completely different thing than what you originally wanted to say. But anyway...

If you could filter it to 1nm that would mean that it already contained a 1nm line and it was cancerous to begin with.:whistle: You can't add stuff with filters, you can only remove stuff.

A BOMB price is a price that you have no idea how much it is. Or at least that the conclusion I draw after this guy states "BOMB price" in the title and then fails to provide any figures about the price.

Well the only 4 pointers is because I can't afford more.I have a lot of laser stuff on the wishlist but I don't really have the money.And I have 3300 posts because I participated in a lot of serious intelligent discutions (and when you add the 85% spam posts lol....) :whistle: But considering...

I only made 4 lasers: 1 red , 2 blurays and 1 greenie.They're all still alive lol.I haven't killed anything:angel:

A 10 or 20mW should do it, depending on how sensitive your sensor is.Your main concern is divergence.At that distance the dot is gonna be quite big, but if your mirrors are big enough (and bigger mirrors will be easier to allign too) you'll only need an additional lens right in front of the...

I wonder....Can't we host the chatbox on some free server , then Avery can use a frame on the top so it would be similar to how it was? :undecided:

I dunno....It was my first impresion that he wants laser pointers with caps that project the logo for the purpose of giving out free souvernirs like you would give pens and lighters with your company logo.:undecided:

You mean you need some of those caps that project an image like you find on 2 dollar pointers? You need some custom made diffraction gratings.Those are obtained through a series of microscopic and very precise scratches on a flat glass or plastic lens. Unfortunately I am not aware of any company...

Yes! of course! An ingenious device that somehow powers some sort of fluorescent or incandescent bulb using energy that it draws from the mains 60Hz 120 VAC power outlet.The lamp would have to be constructed in such a way that it emits non-coherent radiation in all directions with a large...

There is no second beam.The second "beam" you see is the wire being illuminated by speckle around the initial beam as far as I can tell. And I agree with cyparagon, it most definitely is not perpendicular.

How come no one posted THE video ? http://www.youtube.com/watch?v=NqqeX0opcO4

Heck, I have a pocket mini phr build I'm willing to let go for $150.I'll throw in a 10x10cm curtisium GITD sheet for free. I'd give you the batteries and charger too but I think I messed them up with 220V (although the charger did say 110-220VAC :undecided:)

Yes you are correct. If your viewing direction is perpendicular to the beam you might not even notice it, while if you were looking down the beam at a narrow angle it would be plenty visible.It's because of the scattering in the air and particles suspended in the air. If you are looking away...

Well I got a lathe and a grinder in the basement, and lots of drill bits and drilling machines.I have about 50-60cm of aluminum rod that I got for free.So for me it would just cost the time and effort.I'd definitely be one of those who would build a host rather than paying and extra $100.That is...

Well I don't know what's up with the gay ad lol , it's completely irelevant. But anyway, they're not in the posts , they're just to the right of the post.... When our posts are gonna look like: "So I built a new tec cooled labby today.Tunable Diode Laser Single Mode, Narrow Linewidth Highly...

On the tape as far as I can tell.
