Ok, here is the video fresh as of a few minutes ago. Laser is reading right over 2500mw and staying strong.



http://www.youtube.com/watch?v=95MUy2IyCNw&hd=1&t=1s


I just finished a build that I would like to sell. here are the specs...

The host is a 2c sized mag that has been shortened and re-threaded for a pair of 18350 cells and the head has also been finned.

Jib 1.8a driver

M140 diode

405-g-2 lens

2, 18350 lithium cells

I machined 2 separate sinks for this laser. If you are not familiar with the c mag the space in the head is much larger and the aluminum sink for the diode is huge. I also machined a separate sink for the driver to sit on and once the driver was bonded to the sink I bonded a solid copper sink to the top of it as you can see in the pics. Arctic silver thermal epoxy was used for all bonding.

I finished the build on this last Thurs (2/9/12) I metered it tonight (2/11/12) and this laser on my brand new laserbee II metered 2566mw. On the chart you can see where the power jumps up at 2 points. This is because I did not have the beam all the way on the sensor. I had to adjust it twice to get it all the way on the sensor. All components were brand new and the total run time is less than 3 minutes at this point and I do not plan on running it anymore.

Asking $300 shipped with insurance and tracking.

Here are the pics....

Thanks for the support guys. One thing I will mention is that I had the beam so unfocussed on the thermopile that small pieces of it were hanging off either side even when centered. I have no doubt that this will meter over 2.6 if I were to focus it a bit more but I am scared that I am gong to fry the coating on my sensor.

I am very interested in this unit of yours. Tried pm'ing you but you didn't reply. I would like to know if overseas shipping an option for you and if so, how much would you be charging for the Tracked Shipment overseas?

I know you would not want to switch on this unit any much though I am very concern about its performance for burning capabilities, where I need a laser better than my current MagLite 2D. A laser unit that can sustain ~2W output power after 3 mins of constant switching on. Please let me know what kind of heatsinking features you have for this unit.

Or you may like to reply my pm instead.

Thank you very much. Hope to hear from you very soon. Appreciate.

I did reply :yh: I do not think it is a secret that running these diodes @ 1.8a is pushing them pretty good. I would like to keep the runtime as low as possible for the new owner. However, I will run it for a 1.5 minute run IF it is a request from several potential buyers. As of right now interest has been very good and I have several people sending PM's.

thanks just received your and also replied.

I understand you have potential buyers, I accept your above advertisement and I decided to buy this unit from you. However I wonder if you accept paypal and also if you provide overseas shipping? Amidst other buyers, keep me informed if I won the chance to buy this from you, tyvm.

That sounds good I need to see what it is going to cost to ship to you. Can you send a PM with your address. I may be only able to cover some of the shipping if it starts to get outrageous. Also I do accept PayPal.

Will you please re-meter this laser and make sure you have the entire laser on the meter during the whole process. If I were a buyer I know I would be concerned that you could have added a second and then third laser to the test because that is exactly what the graph would look like if you were to do that.

Hi DK, I agree in this I didn't ask you for this, would you please do this once more as specified by yobresal? I owned two Thermopiles, one Kenometer Pro with data logging, and a nospin with very clear led display very suitable for taking videos,

It would be ugly if I testified it to be out of my expectations. Thank you very much.
