Hi Jay,
Nope...still not done, but I did start on it. I do know one of my new MXDL's has the 3 ohm resister, but I had already decided I am going to use a 3 ohm resistor since the diode is a HOT one. So yes, I will be using the hot diode with the 3 ohm resistor. I am hesitant to use the 2.4 ohm resistor which would supply 520ma's to the diode...since it is a sweet diode I want it to last for awhile. As long as I can get greater than 300mw's I will be very happy.

Please post back! I am guessing....320mW's. Glass Meredith right? I have one that's 309mW's, and I know yours is a HOTTER diode than mine...
Jay

what is a hot diode? is it one of those phazor things? would you need a lasrger heatsink for that?

Each diode may differ just a little. We figure that the open can diodes average between 290mW's and 310mW's. That's with a Meredith glass lens @ 420mA's, heatsinked. But Gazoo harvested an EXTRA nice one. He is getting above average readings from it. I wish I had it!

Gazoo, have you had any focussing issues with the Meredith glass module? I have had two that I had to modify. Take a quick read of this post:
http://www.laserpointerforums.com/fo...966870/270#283
Also, in my 'Heatsink Tips' document that I have linked there, I show another 'pointer' for the Meredith's that I have found. I am curious if you have found some of the same issues that I have...

Well, the thing is, the difference between being in focus, and being way out of focus is so minimal. The modules are designed for the 9mm diode cases. Which I have never even tried. I'm sure the focus depends on the diode as well. I think that for the most part, their modules work just fine. Maybe I just got a couple that had the 'skirt' too long or something...

Jay, I have not had any issues with the focusing problem. In order for the ring to screw down far enough, everything must be seated and aligned perfectly within the module.

I do know you have had issues with the module but I hope it was a fluke and Meredith has corrected the problem. The last module I received a couple of weeks ago focuses very nicely.
