need RGB parts suggestons

[carlos3621]

Thanks for all the info,, seems that the more answers i get, the more debated this issue becomes.
o.k. lets just say YOU were building an RGB for yourself, with 3-5 watt output. What components would YOU use and not just wavelengths and powers , but also what brand ?

keep em coming guys, and thanks for the replies

The brands stated above are all reliable units with good support, choice would have to be your a personal choice, we don't want to be upsetting any of our resident supplier friends.

Hi,
Just a couple of points to remember..
If you buy "off shore" that's where your warranty is... "offshore". Therefore the normal conditions of warranty are somewhat vague, however one this is for sure you will incur freight costs if needed.
On the other hand it appears you are looking at a significant spend here in dollars.
If it were me I would approach the manufacturers directly as you may qualify for some discount for "bulk" buy.
All of the ones I have listed will deal directly with you. However remember the support issue they are thousands of miles away.

Who would I use ?? no doubt, Arctos... but who owns a bank ??
I have found Bridge of Laserwave very supportive.
You can get the websites from google by brand name.
There are also some very good "retailers" here on PL. like Lasershowparts, One Stop Laser Shop, and a number of "home based" part time retailers. be careful who you pick as you may see some debate at the moment on here. The ones I have listed above are proven good ones there are other good ones too..

Re the 445 vs 473 issue. Do a search here on PL, we discussed this subject in some depth a few months ago. Its not as simple as some say. Europeans rarely use 473 in their laser.. why?? There are technical reasons, I am not an optics expert so some homework on your part may well be worthwhile.
I do know there is a "bump" in the color aspect of the eye at around 445 which helps this. ( I posted a picture of this a while back here on PL)
The purists say it makes better white, others say it makes an Ice blue white.
Hence why I am using both and mixing to suit. Throw in some green by using Pangolin software (my unashamed plug as a Pangolin dealer) and I "should" have the best of both worlds. ( Lets see)

Good luck

Im waiting for some replies on price quotes for the arctos and kvant units first,,, depending on how expensive they are,, i may just have to place an order with Marc (laserwave) ,



thanx for the feedback ,

If you can afford OPSL's (unlikely from your last post) get OPSL. It delivers some of the most amazing colours at wavelengths no other form of solid state can deliver.

A quick look at video's and pics from "Awakenings" (Netherlands) will convince you.

If like most people you are stuck with conventional units, then look to the suggestions above as to good brands.

to: White-Light,

what components are you using for your RGB ?
is that your projector , on your avatar pic?

I would buy a Kvant Spectrum... with the CT6215s. They go from a half watt to 20W I think... I love my 1W.

Afraid I cheated on that one and got the pic off google. I only have my hands on a cheap RGY. If you want to see the relative colour balance, try some videos. To get you started:

For a multiwatt RGB with what appears to be 473nm blue, try the Ministry Videos:

ftp://plftp:ildaswap@ftp.photonlexicon.com/VIDEOS/Ministry/Best Demo.wmv

(Will take time to buffer). I believe from the colours this is 635nm, 473nm and 532nm but you'd have to ask them to be sure www.ministry.sk The video will probably wow you but don't get distracted by the production, its the colour balance your interested in. Best to watch it to the end as there are some pink / purple mixes towards the end.

For the 445nm option, this is the Kvant 1.4W which All and Pelosh have, I believe it is 635nm, 445nm and 532nm (maybe Pelosh or All will correct me if wrong):

ftp://plftp:ildaswap@ftp.photonlexicon.com/VIDEOS/KVANT demo

The latter file might need you to watch it in BS.Player (a free download - google it) as it is in a proprietary camera format I believe that won't play in Windows Media Player. You might need to click play a few times in BS and be patient as its slow to load. Bets to watch fullscreen as well on both videos.

Apart from the difference in strength, there is a difference in colour balance according to my eyes to different ends of the spectrum. Its all personal preference though as I said elsewhere.

[White-Light]

Please explain how?

You are right Pitt. I stand corrected. Pure Yellow is a mix of red / green so is unaffected by the blue. However, that end of the spectrum seems more muted to me on the mixed colours with 445nm in the mix guess that's more what I meant. I do personally find the yellow a little low on punch on Kvants though. Why that should be I don't know. Can't argue with Kvant quality. Very nice projectors if the colour balance suits you.

The red in those is 642nm...
