New kid on the block? The 12x BDR-S06J

Hi All,

I've been sent a new source for 12x BR diodes so here are some pics and output info. It looks like it could be a, "New Kid on The Block". [EDIT: I won't edit the title as it may confuse but... It seems this may not be the BDR-S06J sled but the 10x sled from the LG drives posted here -

http://laserpointerforums.com/f38/hello-lg-bh10ls30-10x-47723.html

However, the figures still look pretty good. Of course there is not much known about how long they would last at the levels I tested at. No failures of either of these diodes during the test though and they initially look to beat the graph for the SF-BW512L 12x Lite-On diode I tested from the GB. Again, only preliminary results at this point. More examples need testing.]


The sled is, as the picture describes, a BDR-S06J, (at least in emails it's described as the BDR-S06J but I guess looking at the box it could be sold as a BDR-506J? It's supposed to be from a 3D player? Whether this will demand different characteristics from the diode I am not sure but I doubt it. Are there any 3D burners out yet? Would a 3D reader need to be this power? Some interesting questions here.



Both sides of the sled. The one I actually opened is on the left and didn't have the bar code sticker on the reverse.



Closer front shot...



... Rear shot...



Skinned. This sled has two seperate shrouds and I don't think you would need to remove either of them to get at the diode. It is a dead easy sled extraction! (You can see the little chip on the board there. It's thermally bonded to the indent, in the same orientation, on the shroud at the bottom of the picture.)



A closer look...



Rib cage opened up...



Bluray diode is bottom left...



Red diode in the non-5.6mm package is top right...



Both diodes, finally together. Ahh! The red is the one with the blueish AR coating. There is plenty of room to get a good grip on the heatsink from this BR. Clamp one side in a vice, and use a back and forth twisting motion with a set of pliers to weaken and slowly break the heatsink. These are not brittle but quite soft and work harden similar to lead so again, extraction from the heatsink is also easy for these.



It's interesting to note that the heatsinking compound in this sled was still either not properly set, or should be in this semi fluid state. Be cautious of this if you are extracting as this stuff will easily transfer to diode windows and optics if you're not careful. See the thumb print?!!! That's how soft it still is.



The BR diode has a curious green lining to the window. I've not seen it before but I may just have missed it... ?



Rear markings... They've even labelled the positive pin! (I think this is just an accident but it does look like it doesn't it)



The final reading! [EDIT: Again, ignore the peak value. This is due to tuning to 500mA. A little overshoot on current, (3-4mA), then paired back... ]



Some outputs for this diode are below. The rig used a LaserBee I at 150mm and a Jayrob 405-G-1 lens.

Pretty nice figures I think. I'm sure a graph will pop up shortly and I'll post that when available.

I can get hold of these too and would do a GB if anyone's interested as this gives us more options for 12x BRs. I know it's only one set of readings but I will post the other sled output as well at some point.

Thanks for reading...

Re: New kid on the block! The 12x BDR-S06J

It looks like it peaked at 772mW...
What is the price of one of those Sleds...:thinking:

Re: New kid on the block! The 12x BDR-S06J

Thanks for the info : )

Re: New kid on the block! The 12x BDR-S06J

I think what is the most impressive is that it got 767mW@500mA.

I got 900mW out of my Lite On diode but I had to put 720mA into it.:gun:

@500mA on the Lite On you are 680ish

Hey Jerry, in another thread showing results for the Lite-On sled there are similar discrepancies. The peak values for both threads should be ignored in this case as they are ramp tests.

To expain, for those who don't know - The diode is hit from cold at 0mA, ramped to lase threshold and then upped in 25mA increments without a break. A little overshoot of just a few mW will give a false peak value and tuning to 500mA in this case overshot by perhaps 4-5mA giving that peak value. The comment has been edited to ignore the peak.

Good point Jerry thanks.

At this point I am trying to work a deal for numbers so will get back to you but they shouldn't be any more than the Lite-Ons.

Jerru, what have you done with Jerry?

^ You're not the only one who was impressed! I await a comparison graph showing both the Lite-On readings and these. I think I'll drop BB a line...

Re: New kid on the block! The 12x BDR-S06J

I would like to see you do that again but leave the HP lens off so we have a base line for the diode it's self.

Re: New kid on the block! The 12x BDR-S06J

Very impressive readings. I am amazed how far these diodes have come in the last few years. Subscribing to see what they get back to you with a price range. :evil:

Re: New kid on the block! The 12x BDR-S06J

This is the same sled as the one from the LG 10X

Peace,
dave

Re: New kid on the block! The 12x BDR-S06J

It definitely looks like the same sled as posted here -

http://laserpointerforums.com/f38/hello-lg-bh10ls30-10x-47723.html

... but same diode? Looking at the graphs and plotting some of the numbers off this one appears different.

I can do that but it'll only be inside an Aixiz so not all the output will be caught on the the sensor. I thought standard practice was with the lens for this reason?

Re: New kid on the block! The 12x BDR-S06J

It doesn't "look like" the same. It is the same, right down to the little + (or is it an x ?) at the peak of the square code.

Diode from an LG 10X


There is enough diode-to-diode variability to cover the difference in the IP/OP graphs

In addition, we have found that since the introduction of the 8X, we can run the 405nm diodes WELL above its "safe" current without observing a kink. Just because we get an IP/OP graph that will go to 700mW does NOT mean that the diode can be run at that current.

I'm not saying that the 10X cannot perform at the level of a 12X. Not enough 10X's have been graphed to know.

However, think about this. The BDR-S06J isn't scheduled to be released IN JAPAN until November. What do you think the odds are that there are already surplus sleds bouncing around?

Peace,
dave

You make a convincing point! Time to tear into the other one to get the figures off that too and add to the info pool...

Not as clever as before but still just out performs the SF-BW512L test.

I have the Lg-10x I harvested earlier this year and there is no doubt it's the same diode. They both have the same bar code and plus sign or "x" next to the positive pin. I have approximately 7-8hrs on it @ 380ma and let me tell you it's a hot little diode, lights matches from the bare side and doesn't show any signs of significant degradation.

I wouldn't be disappointed that it's not an undiscovered diode, it is still very good IMHO! If you don't mind my asking, how much did you pay?

Comparison graph between the 12x SF-BW512L and the two 12x BDR-S06Js.

Thanks BB! Top stuff!

Don't get me wrong folks, I'm not disappointed I've not found a new diode but this is a new source of a diode we may already know. Other than extracting them from complete drives at obvious financial cost this is another option. Not long ago these were topping $100, still with the privilege of extracting them yourself. The ones tested here were samples I didn't know I was getting!

Knowing just what they are will hopefully give some leverage to driving the cost down and at the very least let's us know that these don't have to be sourced from complete drives anymore.

I've driven a GB price down below the other 12x sleds but I wonder if the few bucks I've achieved so far is enough now the, "10x", label has been put on it? Maybe I can push it lower because of this... I know honesty is sometimes a rare commodity between the west and east but looking at the graph for these limited tests, (plus, check out the ones in the link to the 10x above), they show pretty similar lines. Longevity hasn't been tested of course but neither have the 12x in any numbers.

Of course, I don't like to think I've been told one thing when another is true but frankly, with these outputs, I don't care what the seller wants to CALL it, it suits my purpose and pocket as long as I know the risks.

If you don't agree then fine, you now know they are out there and available as just sleds so go make the deal, but if you want me to try and open the channels for these things to the forum, at a sensible level, then I will.

I thank Dave for letting us know just what these sleds really are. I hope the figures go a way to matching up a sled to its expectation too.

I have primed the waters for a GB on these or, if these are to be left alone then another one for the SF-BW512L. I'll get some figures for another output graph to come tomorrow on that, (if you're not busy Mr. BB! )

This is a positive move forward I think, not an operation for anyone to get stung.

Good news, yes?
