don't forget, my thread is still up. if there are no more takers, and pman wishes to apply his donations over and over, he's gonna end up with a really huge chance of winning it. I'm enjoying having it around in the mean time, it's quite pleasing tho the eye, especially now that I've got the 405...

best state:whistle:

um yeah it'd be super visible. especially with corrective optics but even without. about the only ones that couldnt be seen in that situation are low powered reds and violets. redcowboy is right. best not to do when they could be in the sky. only time I point at the sky is when I'm out in BFE...

most people who want to use one of mine no longer want to after the safety lecture I have to give. once I did go over everything I could think of, and handed a friend my 50mW 589nm. you know how when changing targets outside you should switch the laser off, change targets, then switch it back...

it was IE

that's one sorts issue with mine. hoding up all that weight is just the g lens in the module, but if I hold it by the head, which I often do as that's where the weight is, I can use a finger or two to keep the FA steady. you say the g 7 lens are near the end of the module when threaded. does...

Ehgemus made it for me before he quit. I had him custom order the 2" diameter copper for the heat sink and I explained how I wanted a focus adapter made for this, and sent him the expander adapter so he could tap the focus adapter. the little filler piece for when the BE is not in use was his...

pretty sure you saw these, but here's my setup. big ass heat sink. of course, the ple-pro I got the expander with is designed for it. I can however use this focus adapter on most of my units to use the expander with them instead, but on all but this one and the dominator it looks a bit silly, as...

yeah when I use it, I make sure the expander walls arent clipping the beam. the result is an expanded rectangle but I could swear I can still focus the beam to infinity with the expander. i've gotten small spots with it this way at over a mile, I didnt notice any waist, or negative divergence to...

are you sure about this? both my nubm44 and my 1W 520 seem to be able to focus to infinity regardless of going into the expander focused. dang you, now I'm gonna hafta check next time I'm home

I'm happy enough that it makes the nubm44 go from ribbon in the sky to something more resembling a laser beam. it does really well on my 520 PL-E pro, I've no doubt it stays visible for miles. i have to defocus the 520 to fit the beam in too. really, only single modes stand a chance of making it...

oh i see, 520 indeed. too bad. I've had fairly good luck ceaning diode windows. the 9mm and 5.6mm diodes are easy. the tiny 3.8mm diodes can be tricky, but i'ver cleaned those too. though none I've cleaned had something burned on. good luck with that

looks like the beam on your 532nm is split, doing TEM01. my spartan had a similar problem fter I dropped it once

well good luck with that, i'll be watching. i dont have a set of cylindricals yet, i only use the BE. it takes away a big percentage of power unfortunately. i can see how fitting the beam into the BE with the cylindricals would be tough. waiting for someone to realize the potential of a design...

I coulda told you it'd clip using a g2 set to infinity and the nubm44. on mine, I have to defocus the laser so that part of the waist goes into the expander. the output of the lens is not the same as the lenses diameter, it too is cropped by the inside of the expander. the ideal power capture...

no, it's got a 300mW 445 in it, and a 100mW 532 and 638. certainly of no interest if harvesting diodes is your goal moot point as it's sold now

sorry, I've tried to update the title, not only in OP but other posts, it still shows the original title. I'm selling my LK PD2 projector for $300 plus shipping. price reduced from $400

price lowered :bumpit: thread title STILL wont update. might have to make another thread

If you found a good way to make an add on for cylindrical lenses, that would be killer. a design that allows the removal of these for max power up close burning , I'd love. I was thinking if the focus knob was flush with the edge of the heatsink, cut into the sides of both, forming grooves...

800mA? damn, I've burned em out @ .6A or .5A good luck
