13W RGB ???

[losttribelasers]

Building two 13 plus Watt rgbs and wanted to get some views on the lasers i am thinking of using. Here is my possible parts list
3.2W 640 Red (not sure if i want this or the 635/660 kavant, or even using the 635 kavant)
6W 445 Blue (kavant or have my friend make one for me)
4W Vishio 532 Green
6215HP scanners (or DT40 pro Wides)
LT1000 projector case
Would like any advice. This will be my first RGB'S from scratch so i am looking at some late nights. Nothing is set in stone yet. I need two outdoor rigs for some upcoming shows.

DT40 wides are killer scanners but I don't think the beams from the kvant red and blue will fit on the 3mm mirrors.

Hi LTL -

Welcome to PL..

I need two outdoor rigs for some upcoming shows.

Where are you located? (US or Europa or.. ?) Will somewhat influence what recommends are made... and there will be one other factor...

cheers..

I would guess the LT case means its US. the DT scanners can use a bigger mirror if needed. I believe kvant no longer supply 640 reds and now use the 637 diodes instead. Your powers won't give a great white balance ( not enough red ) but should be great for aerial beams. Might be worth getting some advice about the >2w vaisho heads as a few people seem to have problems recently.

Heh, thanks, Nort, but I'd like to hear from the Op on that, for 'other' reasons... ..besides, you can live in Antarctica, and order an LT from OSLS, so..
...and I can think of at least one PL'er that owns an LT, yet lives in Brazil, so ownage / purchase-plans don't automatically = geo location...

..Señor LTL?

cheers..

Sorry I wa just working on the assumption that you may likely choose an alternative if you didn't 'have' to use something like the LT. Tuppence says the OP is in the US.

yea the beams are going to be 4-5mm thats why i was leaning toward the ct6215HP's

I want the power for the aerial beams, these are mainly going to be just used outdoors.

[losttribelasers]

Great site BTW guys, lots of great info!!!!

Ah, ok, then... Please allow me to kindly introduce you to our fantastic 'Wiki', http://www.photonlexicon.com/wiki/in...dies_in_the_US where you can find all the resources you need for Variance-info, (..I will credit-you with the assumption that you are operating legally, under a Variance... ) even State-by-State, for those that have Regs.. ..and, in-particular, (since these puppies sound like they are headed-straight Outdoors, as you say..) what you'll need for FAA-filings, here: http://www.photonlexicon.com/wiki/index.php?title=FAA

..Now, you are more than welcome to go and tell to 'piss up a rope' which, is no problem, I can handle it.. ..but, you're right - this site *is* an incredible-resource, unmatched in all the Internet, imo, and, as-such, you'll find the community to be soooo-much more 'helpful', if you are one that 'helps us' (..the US pro-show producer-community..) by operating Varianced and upholding the regs - especially for Outdoors...and at 13+ Watts... I, for one, would thrill to find that you are a 'seasoned vet' of pro-showdom, current on the Var-thang, blah-blah, and you're already all-hooked up with the FAA, etc, etc... We just *love* to help such-like kin...

Anyhoo, will look forward to hearing back from ya - perhaps a brief bit of your 'backstory', too... we all, here just luuv a good / crazy one ...especially if there's pix...

cheers...

Well, YEs to all at one point I held Variances in texas, arizona, new york and of course the FDA. I have had the feds, arizona (in my opinion the worst) and texas crawl up my arse even come to my shop and inspect evry projector I have and Not once have i ever had a violation, not even a warning. I have even had the arizona guy make me take over another laser companys equipment (in the middle of a show) after he threw him out for shooting beams in a parking garage. I have been doing shows since 1999. Tim walsh is in my backyard so you bet I have the right stuff this is just my first attempt at building my own RGB , but in no way is it my first rodeo in high power lasers (ahh the good old 300 LBS ion days). I dropped out of the lasers for awhile (babys will do that) but missed it so now i am getting back into it. I have done lasers for everything from dell to Ultra. traveled allot for awhile to the point i hated hotel rooms. If i missed anything just let me know. And i thought you had to be certified crazy to own lasers , at least thats what my wife tells me. IMG_0178.JPGhouseofdreams.jpg

Hey LTL-

GREAT pics and it seems you know your Sh*t. GOOD!!

the 637 KVANTS are BEAUTIFUL! excellent beams and divergence is great. I have a few similar projectors that you are building. Mine is-

5/640. 3/532 and 7/445. this puts out a SERIOUS white! Quick vid if interested: VIDEO (Pardon the music. it wasnt mine. lol)

i would try to steer you away from the 637/660 mix only because like you said you are interested in mostly beams. So, go with just 637. Its brighter and you probably arent concerned with a dual red color pallette. Go with raw power/brightness.

and the DT's are worthless with this power. the mirrors literally melt. (have 2 sets here to show for it). dont invest all of that money into a high end RGB and throw a weak link scanner in there. go with Eye Magics or Cambridge. The DT's are an ok scanner, but their coatings ARE NOT broad band coated at these powers.

If you need any info and/or pricing for scanners, lasers or optics, let me know. I am a dealer for KVANT and pretty much anything else you would need.

I can vouch for LTL. He took over the guy's outside lasers, and I got the inside ones. Gotta luv AZ.

...Tim walsh is in my backyard...in no way is it my first rodeo in high power lasers... I have done lasers for everything from dell to Ultra.

Say no more... and any friend of Tim's is automatic 'family'... ..but I hope you can appreciate my 'motives' in asking, yeah?

..You might also know Sir Steve Janders, of ShoCo-fame... (photonbeam, here on PL..) he's right there in Texlandia, too... And, you've got plenty of PL-brethren, right there in yer 'backyard', too... though, yeah - TX is a bit of a 'big backyard'... I'm sure folks will be along, soon, to chat-up 'TexLEM'... don't miss it, if ya possibly-can..

traveled allot for awhile to the point i hated hotel rooms. If i missed anything just let me know.

Coach-class and Budget Trucks...

And i thought you had to be certified crazy to own lasers...at least thats what my wife tells me.

You Sir, have a Beer coming to ya...

RE: your questions, I'd side with Marc on the 'brighter' Red, and if ya can at-all afford to go with RGB Lasersystems (Hungary) or Kvant, for Green as-well (vs a 'ChOEM'.. I opin you'll be much-happier in the long-run... you know how it is with pro-show werk.. 'Pay now or pay later'

Anyhoo, as-to the galvo-question, too, I'd heartily-recommend you stay-away from the 'Chivo's and I'd recommend the Eye Magics, over the CTs for a very specific-reason - since you're planning on these for mostly-aerials, you really don't need the 'butterier-smoothness' you get with the CTs, for Graphics, and the 'EMS' will handle nearly whatever aerial-fx you can throw at them.. (..And they do a great-job for Gfx, too.. and, best of all (..and probably most-importantly, for Outdoor-gigs..)- if you 'overdrive' them, with too much 'detail' / pps, and/or call for a *huge* scan-size, they won't 'collapse', like the CT's are prone to-do, thus resulting in a static-beam not-good for keeping the 'skys-friendly'...

..Unless you plan to incorporate a 'scan-fail' sys, based on the PD-feedback (..which, would be kinda 'overkill' for an aerials-box..) for dealing with that CT-trait, the EMS will be your best-overall 'value'... imho...

Also, (imho.. I'd recommend going with some of the old-skool Ion-dichros you may-likely have at yer disposal for color-comboing, vs the 'cheapie' ones, so-prevalent nowadays... I've seen mind-blowing efficiency from some of those 'older' dichros.... (ie: 0.25-0.5%-losses

Lastly, I'd highly-recommend going with vertical-drive combiners, ie: http://cgi.ebay.com/ws/eBayISAPI.dll...m=170312166714 - will save a bit-more-space than the 'pass-thru' style, you can work-in 'external-access convergence-adjusting'-ability (mission-critical design-feature, imo..) and... your fingertips will thank you..

LTL - look forward to hearing of / seeing your Build-ventures!...
ciao

[losttribelasers]

Thank you, Nice video as well. I will post a revised parts list. anyone know the cost of the new eye magics?

[losttribelasers]

Thanks for the too bad I went sober three years ago will be posting the pics as i spend the countless hours building them. You gave me a good idea, i did buy a crap load of old dichros from ryan and steve, they were left over from the old pink floyd laser shows (got the original projector boxes too why I have no idea!) Gonna have to dust off the old boxes in the attic to find them all. Wont have a scan fail this build, def something to think about later though. I will look into what all it would take to install one if i go with the ct's. as far as the green kavant or rgb laser green i will have to see what they are running price wise. I have two melles griot micro yags but i wanted to save those for two more smaller rgb's.

Mr steve, hows AZ? is that new chick still the BRC officer? been a long time!!!!

[gottaluvlasers]

LTL-

Be careful with older dichros. I will have to disagree with DSL Jon a little bit on this one. Older dichros have proven to NOT be very efficent with newer wavelengths of lasers (especially 445 and 637/640) due to the multi-diode/random polarizations of beams. there may be some exceptions, but i know OSLS has gone through HELL and high water to develop a high efficiency dichro for newer wavelengths and multi-diode random PL lasers.

Just an FYI

Well, then,

Be careful with older dichros. ...there may be some exceptions...

Here, lemme help you rephrase that: 'Feel free to experiment with some of the older color-box dichros, but don't count on them all-being the most-efficient'

I can agree on the 'Green', actually - what we use-to use to separate a nice 'leaf-green' from an Ar-beam, actually is not all that great for 532... *but* I've found the dichros used on the Kr-line (647) to be quite-efficient at passing 640-red, and R-ing the G+B..

...don't remember the exact-numbers on that one, but others have shown surprizing-results... one outstanding example is what we classically-used to use to 'separate' (T, not R..) Yellow, from a WL ..at 45˚, that stuff? OMG, ie: I shot 2 full W of 445 at it, (summed from 1-H and 1-V diode..) and it only 'leaks' 5mW, (..on a calibrated Newport.. ) - that's a quarter of a percent, by-my calcs... pretty dern efficient, I'd say..

The same-stuff is only about 98%-efficient at T-ing 532, so, not-necessarily *the* best for 'summing' the two, but, certainly great for 45-ing the 445, at the 'start' of a train... and usually, 532 is the line that most-peeps have plenty of surplus-of, so, can usually 'afford' to lose a few more mW', than-with R or B...

..I guess the only point I was tryin to make was... try before you buy...

Lookin forward to seein yer rig-pix, Chief!
