It is Here.!!!!! 300mW "635nm" Mitsubishi.....

[DTR]

I am really thinking I could have sustained the 650mW @ 700mA but when I turned it to 800mA I got 700mW but it then started to drop so I lowered it a little.

It is all good. I got a little impatient myself and did some testing of my own tonight. Actually out of the 30 units that I got one of the diodes had a loose diode window so I kept that one. I decaned it tonight and mounted it in my Maxsink. Then I proceeded to do some testing on it. I am still really looking forward to seeing the results from Cyparagon especially the wavelength sift data.

Here is a video I made. I will say my current guess is that they can be safely driven @ 550-600mA but I will need to put some more time on one @ 600mA and see if it degrades. Now you are going to love this.:eg:









Test was done with a G-2 lens.

Should I push my freak to 600mA to see what i get.:eg:

???

Simple answer. YES!

I would feel really bad if it died on you... but looks like 600mA is not that dangerous... maybe go very slow with it?

I was Guessing that same as DTR ~600mA was the max I would say but ill just wait 1 more day for some more testing results before i turn this sucker Up>:eg:

But that video sure makes me anxious.


Man where are these 500mW at.

DTR - Was this test done on the 300mw or the 500mw version of the 635nm diode? I just want to be sure because I have two of those on order. I should get them this weekend, can't wait to mount 2 of them with PBS cube in my projector!

300 also are yo gonna use any correction optics other wise you'll lose allot of power with that horrid divergence :undecided:

 

[paulzimm]

Going to try it out at first without corrective optics just to test, I am still keeping my LPC-815's in case I want to put them both back...

I'm hoping for a little bit more... enough to break .5W without using a g1, but an aixiz red instead.

let me know how it turns out i'm planning on putting one of these diodes in my scanner

 

[DTR]

Yep I am not saying any of these currents are safe for your didoes but for those that are brave I can say that it will not LED under 700mA. But as far as how long it will last only time will tell. Maybe 5 minutes maybe 15 hours.

That is going to be tough with a three element lens and these large emitter diodes. The lens just does not get close enough to the diode when focused.



Alright here is another video. Sorry for the crappy quality but I did not want to wait 2 hours to upload an HD video.:evil:

Anyone want to see a 700mW 635 long exposure beamshot.:gun:
This thing is bright as hell.

 

[InfinitusEquitas]

I guess my wallet will just have to work a little harder for more g1 lenses

How is it setup right now... what I mean is are you killing this ld? and if so can you run it continuously without heat becoming an issue to test the theoretical lifetime at 700mA?

 

[DTR]

The runs I have done is with the little fan going but no I can feel no heat from the heatsink after the 4 minute run

Is it just me... or are these rather efficient when it comes to heat. Meaning very small hosts and high powers are realistic:yh:

Edit: Just noticed the pictures... looks awesome.

 

[DTR]

OK you guys are going to shit. I was taking more pictures and thinking that damn that beam looks brighter than my 445's. And I went to look and it was set to 1.4A.

So I said what the hell. It does not start to dim in output till 1.6A.:evil:

Check this out.

Lower voltage + lower current = less heat

What was that diode making at 1.4A?
