Yep, you're pretty close to the 1:1:1.5 ratio there, so that's what I'd expect.
Until CD posted that earlier I'd never seen the ratios he wrote, let alone it being commonly accepted, which is why ive queried it

You are using Bonetti's defense against me, ah?
I thought it fitting, considering the rocky terrain.
Sorry Norty....just saw this question.....I was going from memory.....exceedingly likely to be flawed !!! I seem to remember we have many, many threads on this issue of balance !!
But....then.....we have several new diodes to consider !!!
SO....the current thinking....is ?? Red ( 638nm ) to ?? Green ( 520nm) to ?? Blue (470nm).......... 1.5:1:1 ????
Thanx....It has been several years since I built a projector !!!

Lots of people use 1:1:1.5 RGB. No problem going heavier on the red but it's not essential, but you do need the bias on the blue. I've found the white gets a better icy edge if you have some 445 in there.
I had a projector with R 1.4w G 2W B2.7w where the green went bad and down to 400mW and the white was VERY pink. You need a decent amount of green to pull it out of the magenta/red zone

AAhhhh...OK....So....Let me speculate....Combine a single optically corrected NUBM07E @ 4.0 W @ 470nm......with a Dual set-up of optically corected NDG 7475 @ 2.5W @ 520nm.....with a Dual set-up of optically corrected Oclarro 63193 @ 2.5W @ 638nm....So....somewhere around 9W out the front door !! MMMmmm ???
I do not know if this is what Planters had in mind....being only 9W...for an Big Sky Laser'Opalozza ??? But...it sure is a far cry from a year or two ago !!! Thanx for your
teaching !
Added note...Easy...just PBS double all the individual modules...and then we are in the 18W range....THAT may be the ticket for the Big Sky Show ???

I still think you need the green and red to be stacked as well, with the blue as a dual. 18W outdoors is IMO about as low as you would go for outdoor use. So, while still a project, this is now perfectly practical.
This diode is similar to a 445nm 3.5W, which has larger divergence than the NDB7675. We couple 2x NDB7675 to get 3W 462nm laser with less than 4.5mm 1.2mrad beam. 4xNDB7675 to get 5W <6mm 1.2mrad. This diode can be corrected to be 1.5mrad if same with the 445nm 3.5W.

Does anyone have uncorrected far field images of the old A130/M140 vs the new NUBM07E?
