Laser-wave 640nm Beam Diameter?

[Things]

I'm considering buying a 640nm module from Laser-wave, and I think I remember being told the beam diameter, but can't remember where.

Does anyone here own one? Or know the beam diameter/spex?

Cheers,
Dan

Hi Things,

The beam diameter is < 3.0 mm and divergence < 1.0 mrad.

Hmm, thanks

It'll match my green's beam nicely then

I'm also using one of these in my new RGB-Projector, it should arrive this week! I'll post the pictures of my projector when it's finished

Hey Things

It also depends on which one you looking at, the 600mW has 3.0mm @ 2.0mrad and then there is the 640/635 that has the larger diameter at 4.0 mm @ 2.0 mrad

I've order one of the 600mW unit that should be here this week

Are you sure about this? Because on the LaserWave website it is listed as a ~4mm beam.
The reason why I ask is because on 27 October I’ve bought the 900mw model and was told there was a lead time of a few weeks.
After a few weeks they told me it would take another 6a8 weeks so I’m still waiting.
Now I don’t mind waiting until they can deliver a quality product but when the new modules where announced they all had a beam specification of ~3mm @ <1mrad (http://www.photonlexicon.com/forums/...ead.php?t=8841)

So I’m starting to get a bad feeling about this.

/EDIT:
On the known webshops it is still specified as ~3mm @ <1 mrad:

I have one and I will try to post pictures and measurements tonight for you guys...

i am in the same boat as you, still waiting on my 900mw 640

hey guys-

We are working on the issue we have had with the far field alignement of the beams becoming misaligned. this is affecting almost all 640s over 350/400mW powers. and also some issues with the diodes.

as i told flecom, we're commited to sending out the best lasers possible. we dont want to send out sub-par lasers to just have them be returned and have unhappy customers.

the issues are being worked on and i am sure bridge will comment also. i am not familiar with other laserwave distributors customers 640 shipments and how they will be handled. I am just telling you what the situation is.

any 640s that CT. Lasers have already been delivered are perfectly fine. i thoroughly bench test them and modulate them prior to shipment. so all should be fine.

dont worry though. its being worked on as we speak!

Hello Marc,

Do you know the “final” beam specs of the 600 & 900mw lasers?
Because at the moment there’s a different specification on your website compared with the original site of LaserWave.
I (and probably others) paid for a laser with a ~3mm @ <1mrad beam and not ~4mm @ 2<mrad.

Personally I don’t think it was a wise decision to start selling the new modules before it could be manufactured correctly.
This is also the reason why the distributor where I bought mine did remove the higher powered reds from the list.
