building full color projector need advice on red

[andy_con]

correct a single 638nm diode would be brighter.

but dont forget tight beams look just as bright as fatter beams.

with that setup i made combine two using a cobe and you have 2watts of 660 in a tight 3mm by 3mm @ 1mR beam

Any ideas when that PL GB for the 638s finifshes Andy or pbd? I didn't see anything in the thread and seeing as you've brought it up... It's up to over 130pcs already.

thoughts on this laser? Are the specs good for a laser projector?

viasho is generally accepted to be one of the better laser module manufacturers... looking at the specs its got a large beam & divergence, but thats to be expected from a 635nm laser...

I would look at laserwave also I have been happy with the modules I have gotten from them

heres the 635nm modules from their US reseller I have used

(note: I have no affiliation to laserwave or CT Lasers besides customer)

that beam isnt to bad to be honest, my old 635nm lasever had a beam of 5mm by 8mm at apeture.

just for your into i could build a custom 1watt of 660 with a tight beam for £250.

Huh?

I know it wasn't your GB but as you're over there I thought you might know. Is that what you meant? Or are there 2 andy_cons?

I am deacuerdo with flecom I have a red unit ttl of 900mw and great the square divergence is of 5x6mm usually is something, with touch are never overlapped well, but to the 100%
