Default 18mw HeNe is here!

Wow - 18mw of HeNe is BRIGHT!

Theis tube is pretty much brand new. Not a mark on it or the PSU.

...and now, what I know you really want are - BEAMSHOTS!

Running an interferometer setup:

And just some multiple bounces between mirrors..

And just for fun - in black and white... Its a cool look..

Beautiful pictures Escher!

May I ask which wavelength this is operating at?

Thanks.... It was listed as 632.8nm but I have no way of measuring actual.

Ok, thank you.

Nevertheless, still looks like an amazing color

Default Re: 18mw HeNe is here!

It's 632.8, plus about 3 or 4 sig figs that are pretty much irrelevant. After that it gets hairy without a stabilized HeNe.

Nice tube though Would be fun to test that with some external mirrors

Default Re: 18mw HeNe is here!

I used to have a bigger red, but it was old and finally bit the dust about a year ago, ended up reusing the mirrors later on, but now looking to get another powerful red. I really envy people with a SP127. looking forward to getting one soon as soon as I manage to accumulate a couple more pay checks. problem is finding a place for these beastly things.
