Buying: R-G-B laser combo

[swamidog]

there's no optical correction on those red and blue lasers so your projection will be super ugly.

far field red will look like this: + (this will be twice the size of the blue)
far field blue will look like this: -
far field green will look like this: .

plus the modulation is TTL instead of analog.

also note the lack of adjustments on the pbs cube and mount. did they really just plunk it down into a puddle of epoxy? if that thing is, or ever drifts out of alignment, there's no way to adjust it without cracking the epoxy, tweaking it, and hoping it stays put when you re-glue it.

swami's spider sense says: avoid like the plague.

Okay, but seriously.. honest opinion on this one?

Besides the fact one of the red lasers is off, it runs off
220V AC (and 12V DC), and is only TTL modulation..

.. the lasers look like they are semi-decent?

Yeah, and all those power supplies are just thrown around ..
"Operating Voltage: Green laser at 220V,Red laser at 12V,Blue laser at 240V"
220 and 240 .. huh ??
..and he didn't even fix it up so all the lasers are working for the ad photo ?? Yeh looks like junk too me too ..
"3 available" .. he built 3 .. lol .. I pity the poor sucker who pays 800 bucks for that ..

Yeah, I would remount / change out the (included) optics regardless.
How hard would it be to add beam correcting optics to the red & blue?
Or, more specifically, how expensive would it be? Haha. I wrote the
guy (who is in China, of course) and asked if they sell the same setup
in an analog configuration. If I could get that for the same price, it
seems like a halfway decent laser setup (1W x 3) for the money??

If you guys know somewhere else where I can get 1W red + 1W green + 1W blue
with analog modulation and matching (120VAC) power supplies for around that
same price, I'm all ears..

[swamidog]

no..

without corrective optics (and there's not enough room in that layout), you will not be happy.

In other words, 3 watt RGB lasers cost $5,000+

No. I just purchased 2 X 3 watt RGB lasers from Golden Star for less than $3000 each (each with it's own flight case), and I am very happy with them.

[lloyd33]

LOL. Okay, $3,000. Still 3X my budget.

But just for kicks, do you have a link / pics / specs?

[Stiffler]

I don't know if this is the proper link, but this *should be* a video from facebook showing one of the lasers I bought. It's a terrible camera phone video, but it shows the laser hitting 6 bounce mirrors, 2 disco balls, while projecting text on a wall.
