As subject says please.

Output beam diameter, from the laser, is about the 16-20mm mark.

Thanks

Hey Jim -

Output beam diameter, from the laser, is about the 16-20mm mark.

Well, I know of a good resource for 16-20mm IN, but your CV is like, 40mm, right? Hmm, well, will take a bit of searching, but I am sure there is something out there for ya...

Steve Roberts (mixedgas) will probably have / know of a good resource... Also, I'd ask Paul (clandestiny), he's got lots of good '411' on CVs... I will be checking with a 'laser neighbor' at our NY office / shop - he does denim fading / marking with CO2, YAG, and KTP lasers, and deals with very-large-diameter beams all the time - I know he will have, or, be able to recommend a good source for, a 40mm+ Input Ap. collimator..but it prolly won't be cheap, unless he happens to have something he'd sell... Will advise...

Meantime, here is something of interest...

...Sounds like it would be of sufficient-diameter, and certainly can take your power-levels, but.. ???? At least something to ask-about... Also, it is a good bit of money to be 'playing with' (ie: if it was $50. or something, well, if it never showed up, no big loss, but $325. is
a bit-more than 'spilled milk'... )

Anyhoo, for whatever it's worth, and I'll let ya know what I hear back from our 'neighbor'...

PS - yeah, Karl, you are just too damned-funny, man...
Cheers..

spectronika(spelling) ?

Hey Jim -

spectronika(spelling) ?

Yes, good suggestion - last I priced one of their collimators ...(THANKS A LOT Karl, I'll never be able to say that word again without laughing, now..... ) was ~9/06, and they were €175 (about $250. USD) so that is not too bad, IF they are still that 'cheap'.. dunno...

BUT also, 'member this?...

..well, I kinda-sorta made him an offer, and he kinda-sorta accepted it Sooo, I will let you know how the transaction goes - I'll take good pix / post and list specs, and if you want it, it will be yours for what paid + shipping, etc - if not, well, I have an SDL 3W @ 635nm diode project coming up real soon, so this might not 'go to waste', either-way...

Hope this helps..
peace..

What's the divergence like on that laser? As a Cu vapour laser only needs one mirror to lase, it might be quite bad, and a collimator that reduces beam width by X amount will raise divergence by X amount. You might get more joy out of sending the beam to a diffraction grating to split the beam into low divergence parts, and send each to its own scanner. Expensive, but definitely an interesting show device.

Re dogs, I'd hate to have to measure the divergence there...

IIRC the Spectronika has a beam approx 12-16mm in diamater before being collimated. Their lens assembly might not be wide enough. Doesnt hurt to ask though.

Sent an email yesterday to Peter at laserattractions, Spectronika's UK outlet, and as of yet, no reply!
Dam annoying!

I have now emailed Spectronika direct to se if I can get a reply off of them.
