    Cool

    What is the exact size of the module and what size optics will it take ?
    (I assume it comes with no lens or not very good lens, is this correct?
    Do you supply with a proper invoice ?

    Cheers

    Default Experience with DTR

    I have had many transactions with DTR and have never been let down. I can see him building his own RGB as he has skillz. And is always helping others.

    I also have purchased from DTR (dozens of 445s). Good workmanship and fast turn around.

    DTR,
    Unlike the builders at LPF who are disassembling the module to incorporate it into flashlights, I'm interested in using one or two of these complete modules illuminate a mirror ball in a large dance hall. There are a lot of wires exiting the board what exactly is the drive set up? Is the associated board the driver and so we can "safely" use a lab style PS to supply the current(as in your pics)? If running continuously what is a reasonable max amp supply with the associated fined HS; what if we add a fan? With the included lens can you estimate a beam spread, as in 10 foot throw/ x foot wide?
    Thanks

    With a heatsink like in the video and a fan you should be able to maintain about 1A-1.2A continuous no issues. If you add active cooling/TEC you may be able to bump that to about 1.5A.

    Here is a video I did for 1A with an Aixiz glass lens for 5 minutes in my finned heatsink and one of the micro fans I have. With a single element lens like the G-2 that would bump it a little more than 200mW at the expense of divergence. This is very similar to how they run in the projector but with about 100mA more but just one diode in the heatsink and the fan.




    Divergence will depend on the lens you go with.

    Here is the dot/bar @ 35 feet with a few lenses using a AAA sized battery for scale.






    Three element 405-445 glass lens.

    Just noticed the "Mitisubishi 300mW 635 Diodes In Module W/Leads" on your o.p. Are you going to add the price and beamspecs later (assuming this is a new(er) item, right?

    Yes they are $69 and can be purchased directly from my site.

    These do have a very large emitter but there has been some testing using prisms to correct the beam.

    Here is the data sheet.

    A 300mW for $ 70.00 @ 638 ....and looks like a 500mW coming out for $ 120.00 ????????? Can optics tame this Mitsubishi ML520G71. ??? If they can ????? At this line...one would not need to combine so many...Four of these at 500mw..two @ 445...throw in some green ???? Thinking !!!!!!!

    Sure hope we can tame them. I have built two of the 300mW diode so far and both are about 340mW @ 450mA with a G-2 lens. We did a murder fund and I send two off to a member that has a spectrometer to do some max current vs. wavelength torture testing. Hoping they can be over driven to 400-500mW without issue. They produce almost no heat. He has already done a little testing on one and says they are like the 445 where they shut down at a certain point instead of blowing which is awesome. That means they are really tough. He has not put up the graphs yet. More info to come.

    NO HEAT !!! Great.....All the current goes to pumping out photons in lockstep....to the Coxswain of 635 nanometers !!! If we can just get'em down to 1.0 mRad divergence....it'll be an early Christmas. PLEASE keep us posted !!! A GB to DTW is what I vote for......IF all goes good !!!!!
    Thanx...

    Yikes....now I am reading about a 2um x 40um emitter size....???? Beamshows...yes ?? Graphics ????????

    Yep I was very impressed with the efficiency as well and with the prism details Cyparagon posted over @ LPF he was able to get it to 0.9mRad. He also reported they don't seem to wavelength shift as much as most reds and playing with one tonight I noticed that they do get a considerable increase when you cool them. Will post some info on that tomorrow.

    Anyway I have 2 in stock and 10 more here tomorrow if anyone does not want wait for them to be shipped from China. I also include them in an Aixiz module with leads or just the bare diode(by request) for the same price as the China eBay sellers. Check out by clicking on the screenshot of my web store in the OP.


    Also anybody know why when I do an advanced edit on the OP and try to change the title of the thread it does not work? When I go back and try again it shows it saved it but the thread title remains the same.

    This is very cool. However, I doubt with 100u emitter and .9mrad divergence that the output beam will fit on small scanner mirrors. I don't think that they are concerned with scanners on the pointer forums. Personally I don't object to large slower galvo mirrors but it seems that the high-end lasershow people do .
    Did they say how big the beam was at the aperture? (I may be wrong about the emitter size.. I certainly hope ;]

    That is what we are trying to figure out with the testing. Cyparagon the one doing the testing and a lot of the members in that thread are interested in being able to incorporate these into scanners/projectors. There are a lot of people over there that are interested in more than just pointers but I know how some here feel about over there. I myself am planning on building a nice projector but I still have a lot of learning to do before I get my project mapped out.

    In the end if these can be driven to 400-500mW and you end up having to say cut 50%(25%--25%) of the beam off then use some form of correction to get the rest of the beam to a usable divergence it could still be well worth it and since the projection industry is driving most of the development of these new lights sources I think it is certainly worth the effort to find ways to make these useful to us.

    Thanks for all this Jordan-I told you long ago that you will be doing your own projector someday son- cant wait to see how you will use your great skillz .

    DTR,
    Sorry about not being clear in my earlier post asking about "these modules". I was actually interested in the LED modules that you extract from the TV projectors. Lots of non coherent light to illuminate a dance floor is the goal.
    Thanks

    No problem.


    Alright guys check the thread for the full rundown.
    It starts on this post.
    http://laserpointerforums.com/f50/he...tml#post970935



    Here are the cliff notes.

    First I tried it @ 600mA and got about 530mW with a G-2 lens.


    Next I went up to 750mA and got 700mW.


    Then I took some beamshots





    While I was sitting there taking the pictures I thought damn that looks as bright as my 445's so I checked the current. 1.5A.

    So I said what the hell.




    Ok so 1.6A did not LED it I wonder what it is putting out there.






    Next I ran it for 7 minutes @ 1.5A and it has not killed it.


    Now none of this tells us for sure where you should be running these diodes but it does say they are tough as hell.

    The G-2 is what I tested with. Some have said the 650-G-1 would have even a little more power transmission. The quantity of 635's is down to only one so you may want to grab it quick.(No Pressure) It won't let you order after it goes to zero until I change the button to a pre-order for the next batch that should be here by Thursday next week.

    Here are the different lenses I tested with.

    so, all we need to know now is a bit about beam characteristics and a form of correction and we can forget about LPCs, opnext, NECSEL etc etc

    Can a readily available solution from the 445 camp do the trick? Cylinders maybe? (i dare not speak of a FAC lens, as the answeers given to me last time by two very kind and knowledgable gentlemen made my mind flip... http://www.photonlexicon.com/forums/...-lens-question )
