Hi Everyone,
Sorry for not posting much, just hope this helps someone!
I thought i would post some pics of the layout i am testing for my final laser module in my projector. what i have done so far with the projector lasers is combine a pair of reds and a pair of violets, using polarizing cubes and associated optics. now comes the time for some serious power, two 200mw 12mm modules from NEXBOX360, to replace the existing 50mw labby. this will complete the final step in my 6 Laser 1.3W TEC cooled module that i have designed for the projector.
Here is what i was thinking, by combining 2 hi power pointer modules, using the knife edge technique, i should be able to to have the beam of one module, reflected using mirrors, to set side by side with a second modules output.
By doing this right at the modules output, where the beam is smallest, ie: 1mm, the characteristic of beam divergence (beam diameter increases with distance) would kinda join the two beams, as the diameter increased. if this is a problem then i might try using some optics to overlap the beams.
that said, here is what i did, the layout created/tested on my Bench TEC unit, I Designed, just for setup/testing, the projectors laser modules.
Disregard Time Stamp on pics! oops!
i used a pair of 30mw Techhood modules i picked up for 30USD on ebay. yes these are the SD-10050 4.2v driver boards, added heat sink to Q3 Driver regulator D883, so i could run continuously without worrying about it overheating (2.25mm copper strip ran to module housing). turning mirrors mounted and located. time to power up and align the setup.
the trick is to get them as close as possible without sacrificing part of each beam. what a pain, at first, Getting right on that edge!
Another view of the ailignment
here is some beam shots of the test layout, shooting on the hallway
wall 15 foot away. the beams look as one beam! COOL!
More:
Looks like a go, so i will whip up setup to put the 200mw modules in, while i am waiting on the modules. i post some pics when its completed. sorry no power specs yet, no meter yet!
has anyone tried this before? i mean with green modules? Thoughts and comments welcome!
Thanks for listening!
