RGB build seems I do this every year 10w goal

[LaNeK779]

I have found that when spaced tightly over under the result is less than a .1mrad difference when using 2 diodes. I'll turn down the powers and try to get a real camera to take a picture of the difference at 50' it is minimal. I guess is is dependent on how you define acceptable. I'm a the enemy of good is better kind of guy. This red will be a 4 diode build, and + across each. Time will tell, but was very happy with the first stack once setup. The build is just a test bed right now once proofed, will then have a the mounts machined.

that's good to know, thanks for the update.

Maybe it is the lava cyl pair i am using that is a bit more picky about placement, as they are also smaller in size, especialy the first lens.
I also have dave cyl lenses and mounts, will give it a go in a few months time

Little update on the red and blue, will be landing it on scanners in the next couple days. Looks like raw 3.3W of 638, and 3.75W of 445. I have room and the mount to add 445 correction, just not so sure I need it as it matches red well till 20' then red starts looking better.

And a quick video, will be dropping this into a projector in the next few days.

Well dropped it in, the scanner mirrors are junk. I am landing most of the beam on them, but losing over 1.5W. I was losing about a watt to the old build so this is no par. Anyhow have 6w out now, still have 800mw of green to PBS in. Out the scanner right now is 2.2w 638, 1.1w 532 and 2.8w 445nm. Ill be adding correction to the 445 this weekend.

Still have some tweaking todo but very happy that even tough red looks awful fat it is all but 120mw landing on the scanners. Loosing a lot do,to mirrors. Anyone used OSLS mirrors for china scanners? Thinking about buying some. More was missing in the pics as they were taken at first run withe zero tweak.

I might have missed it so apologies, what scan set are you using here?

ScanPro's with larger mirror i mounted. The mirrors were from a GB a long time ago.

I think I took out my power meter head, it is now erratic. I had added the extra 532 and was metering. So no power shots.
