working on this, once proofed there will be most likely kits offered.

Sweet! Looks great

...thing is, I've already got most of that hardware. I'm just trying to finalise lens and telescope choices to get a beam with a good match for my green, hence my questions.

Any thoughts so far on the 4mm or 8mm Optimas, or are you thinking a different lens?

[polishedball]

I have both, will let you know in the next couple weeks.

Great! Thanks for efforts on this.

Anyone done a PBS combined 12 banger ::: x2?

I've built an a 12 banger ::: + ::: with my screw-loose.... I mean screwless mount system I used the aixiz glass lenses and an aprox. 2.25X tele. fits on a 3mm scanner fine. Only problem is the aixiz lenses are crap with a telescope. Divergence should have been around ~1 but best I could do was 2mRad due to the amoeba like spots from the aixis. I plan on building another in the next few weeks. Was waiting to here on how the optima performed with a tele. I ordered some optima's today. Will report back when I get some data on them with a tele. My guess is I will be using the 8mm FL to keep tolerances in check.

best tip i can give you is dont use plastic lens, use glass only. plastic moves when warm

@polishedball - I'd appreciate any updates on your experiences with the different FL Optimas.

@logsquared - I'm working on a 2 x ::: and would appreciate any further info, data on your findings.

I'm after data and experiences in terms of stacking dimensions, telescope choices and final beam specs.

Thanks in advance

I forgot about this thread.

Sorry to report, I haven't built another 6X yet. Hopefully soon, as I have about 20 LOC's sitting here.

I can say the optima 4mm lenses are great. i put them through a couple different telescopes with LOC's and the spot does what it's suppose to. Optima was out of the 8mm when i ordered.

I may just use the 4mm on my next 6X. I have recently made a 4X with PBS and I think I can knife edge the smaller beam with out too much loss. I used .120 X .0625 (about 3mm X 1.5mm)as my near field beam "window". I should note: I haven't taken actual measurements of the height, just the width. The 3mm comes from visually looking at the spot. It may be possible to use a height of 2.5mm and only loose a few percent. So, 3 over 3 should give ~5 to 6mm X 4.5mm. Probably could go 4 over 4 and get 6X6 if your knifing skills are good Then a 2X scope will get you on 3mm mirrors with around 1.2mRad in theory.

I will be ordering some more optimas in the next few days. Let me know if you need any I can add them to my order. (they have a $200 minimum)

Thanks for that update Woody

Well I'm after 12 of the Optimas. I think given what I've read, I'd be fine with the 4mm FL and then a telescope to get the beam to match the others (though I'll confirm the telescope needs based on your data, the specs of my green and what I'm hoping to achieve with the blue).

I have 12 of the Opnext 63133 diodes ready to go. Although given your observations, 16 would have been better for a squarer beam i.e. :::: x 2. Hmmm, perhaps I could leave space for the extra 4

[logsquared]

I don't think you need all those opnext diodes. I will Pm you my address so you can send me some. I think 6 should do

Well, you will be over the minimum order for sure. Let me know if you need just one to test with before you pull the trigger on 12 pieces.

Can't wait to see your project. Please post lots of pics.
