CT Lasers 21W RGB

[Darcean]

Well, I've finally decided to post about it. I went out and got myself a monster of a laser from Marc. I cant wait to post pictures and get it up and running. I'll hopefully have it in a few weeks or so, pictures soon after, maybe even a video.


5.8W 637nm KVANT red
8W 532nm Viasho green
8W 445nm KVANT blue
Eyemagic EMS-4000 30k scanners



she's a beautiful little monster of a laser eh?

Doing business with Marc was easy, great, and I am grateful for his patience with me! haha

cool lucky man
the question is why are all the big rgb projectors out there so mis-matched ?
you spend all that money ,and to get a good white ya got to turn green and blue down, and end up with a 12w rgb balanced.
or are things looking different when you get in the big power ?

Wow what a nice monster, can't wait to see pics!
I just hope you will encounter less problems than I recently had with my 4Ws from Viasho...

I calculate around 17W of almost-perfect whitelight with this config... At full power it will still be white, but rather a coldish white!

And that's why you find software color balance. You can make your white as you want, and have more punch with individual colors

Ya know, I'll tell you how the white is when I see it =] but I asked myself the same question when I looked up nusalt laser projector specs... for their 30w rgb, edit: here's their specs.. just went to the website: 2.5Watts (2,500mW) 650nm Red
20 Watts (20,000mW) 445nm Blue
6 Watts (6,000mW) 532nm Green.. I was like hmmmm o.O sooo muchhhh blllluuuuee XD

I hope to see one of CT's bigger rigs at SELEM.

Couple things-

1) At this point in the technology, 6W is pretty much the ceiling for red unless you start going to multiple wavelengths of red (637 and 660 for around 10W or so.). But then you fall into problems with combining optical areas (would more than double the size of the enclosure).

2) Also, costs at these powers go up exponentially. As in a W or so difference in red is probably around $3000-$4000 difference. If not more.

3) 6W of red- LOL- 6 WATTS of red. This is STUPID bright. Not to mention, it is a thicker beam (not ugly thick. just multi-diodes so ~4mmX4mm). This beam can be seen in broad daylight, outdoors, on a beach while scanning a liquid sky.

4) White balance according to what? Chroma? this thing is a nice arctic white. and in all honesty, wasnt designed (nor are ANY projectors at these powers really) designed or meant for high end graphics shows where "white balance" becomes a little more important (sometimes).

Will it do graphics? of course. and does them great. But its meant more as an outdoor or large venue Beam system.

If you software adjust this for a "perfect" white, it may drop down to about ~18W or so. However- I would NEVER do that. lol. Turn laser power DOWN?? Is that even possible? lol...

I see everyone is waiting for me...

hahaha I will once I get it =)

I agree with Marc that calculating a "balanced " white is only part of the story. Sure, If your 20W projector is 18W blue with 1W red and 1W green then you have something more like a 3W projector with a VERY exciting blue punch when you want it. This isn't going to be as versatile or beautiful as a 6+6+6, but its going to be a lot more exciting than a 3W alone.

I'm also coming around slowly to the idea that rather than a single mega powerful (read expensive) projector, several less powerful units that unload a single scanner unto a few cooperating scanners is more interesting. The scanners are smaller, faster and can cover smaller areas to further increase their performance. The beams are thinner and the origins are distributed around the venue for more complex patterns.

But...I can't wait to see some pics.
