The other main benefit of rolling your own is you will never be stuck in the field unable to at least attempt to fix something, nor ever need to ask where you can get your lasers serviced/fixed.
That is the invaluable bit imho

You are using Bonetti's defense against me, ah?
I thought it fitting, considering the rocky terrain.
Just a remark; beams leave the prism pair under a small deviating angle, at least if you optimise for magnification and optical efficiency. You can compensate for this by turning the diodes accordingly.
Just don't start drilling until you've decided on your final layout.
Well...I put together a sketch of the RGB portion of what I would do. The emitter size on the NUBM07E and NUBM01T must be close for the PCV and PCX separation distance can be the same for either diode...so a single set of Cylindrical telescope lenses can be used for both diodes.
.
The beam path's are slightly different for the Blue vs. the Green. Jors pointed out that the uncorrected Far field geometry is more divergent for the Blue than for the Green. So...The Blue propagation was given some additional travel to better equalize the FF divergence of the B/G combination. The Red's beam path have been arranged for equal propagation. A bounce mirror is employed for ease of alignment as we enter both Dichro's and the PBS. This attribute causes a very minor OP loss...but really makes the alignment much easier.
.
A small waveplate optic will also be needed on one of the Oclarro beams before it enters the PBS. Good luck ! Enjoy the ride !

Will do, bit more money, but as I can save a bit by using 1 pair for blue/green sound good. Will update the sketch to reflect this.
Great, sounds good.
I can imagine going around in circles for ever, just trying to make it that little bit better. Suppose the skill comes in knowing when its good enough!
Looking forward to it, and feel like I have already got years of experience / mistakes / successes from this place already!
Sounds sensible.
Will update my sketch.
OK, will investigate.
Thanks,
Dupe....
If you're ordering your diodes from Jordan/DTR then see if he can send you a set of projector optics too. There are 2 very usable dichros in there with pretty good transmission and reflection rates and a pair of first surface mirrors which can all be cut down to give you loads of pieces.
