STAND AND DELIVER!!! 2 Watts of Red….Out of the Optics Bed!!!

Andy...I use Quickcad V8 by Autodesk...It is a Autocad lite wannabee !!! Hey...costs alot less...and I get around it OK !! I did another drawing of what the 3 degree off-axis knife edged might look like. Wow....this one will be a real hoot to align....if we need to off axis the beams into the into the C-Lenses !!! Thanx Solarfire for this finding !!

Nice Eight Banger PB !! Yea...Aligning knife edges is a real PITA. BUT...the RESULT !!!! AHHHHHHH !!

Hey Andy, when are you going to unveil the data on your mystery lens?

I was wondering about that too.


Solafire, maybe today if I get time to play with lenses.

Hey Steve-O....would you try the 405 G 2 Collimation lens with the HL6388MG and post the geometry after the prism and at Farfield. If you have a set of Lava Cylinderical optics....I really wonder what they would provide with the HL6388MG ????? Also did you not say the emitter size on the 6388 was 20 uM ??????? I am being a proponent for both the Mitsuibishi and the Optnext solutions !!!.... Perhaps a six (6) multidiode could be done using Cylinderical lenses ??????? See Pic....Yikes...yet another drawing !!!

At the moment both my 405G2 lenses are in use on a 445 glued into place and my 6388 diodes are also glued into housings. I can take one diode loose tho.. I need to buy a 405G2 lens. I think DTR sells 'em w/ fast shipping so I'll order that today and post results hopefully by the weekend. Yes the 6388 emitter I believe I read is 20 um. (The 445s are 14) . Also last w/e I ran one of the 6388s at 614 mA for over 2 hours with no degradation or pwr loss. Looks promising. Not sure of exact p-out because my home-brew pwr meter is "for reference only" lol but it looked to be over 300+mW. I do have a LavaLens set on order, shoud be here any day.

I thought I had read somewhere that they failed with red due to the AR coating for 405.

I thought I read that they were great for red even though coated for 405-445 !!!! ???? I'll have to go back and try to find the posts ..

-edit- from post # 15 on this thread by SolarFire.
Here's a snip from that post:

I got best results with the 405-G-2 with less than 5% loss

SF was testing w/ 658nm diodes. I don't know if 638 will be different.

What about Andy's special mystery lens? I'd like to hear about the results from that before $45 goes out to a 405G2.. (money's tight these dayz ) :/

Here's what I'm working on, I'm probably going to go with the HL6388MGs to give myself more of a chance.

Are you going to telescope that? Not being critical but the beams on your full stack side don;t seem very tight? Sharp looking build though.

Yes I have telescope optics from Edmund and also a wave plate, however the collimator lenses that are installed in these pics are not the lenses that will be used in the build, they are just shitty Aixiz glass jobbies; I was going to use Optima lenses but I'm waiting to see the developments here (also these are old pictures, the build has progressed a fair bit from this, but the project has been back burnered for a few months due to having no time through summer).

Ok, anything for you guys and the cause.. I ripped the 405G2 lens from my bluey, put a MG6388 LD behind it and here are the results (from my very wobbly set-up): 1mm x ~4mm at the ap, and, at a distance of 100 ft with no prism correction looks to be fast-axis no more that 1-2 feet across (I couldn't measure it exactly, as it was too high up in the air. Looks to be about the same as an uncorrected 445 :] (and it immediately smokes electrical tape right out of the aperture.. hehe -still my 1st choice test of raw power.. cant help meself ) ..

Damn cameras are too sensitive.. have to turn the laser output power down too much .. anyway ..

The outside shot was a very clear night.. no fog in the air (of course ) .. :/

The 405G2 with the 6388, nice call CDBEAM . thumbsup.gif
