2w 638nm build

[andy_con]

another build ive been working on (yes im working on shit loads of stuff at the moment)

it uses 4x 500mw 638 diodes, it gives a final beam of 3.5mm by 3.5mm @ around 1.2mR so pretty good

i just been to re machine the base plate and combine the two sets and job done

i feel for you mate but you should have worn your rain mac

My mind went blank Why didn't you combine the beams before (in front of) telescope?

[andy_con]

there not telescopics, they are cylindrical lens to correct the multi mode beam

[Bbe]

they are "x-axis" telescopic, no? The only difference is that the axis "y" is not corrected

[andy_con]

um yeah ok .

just curious why you always use mirrors to knife edge and never the prisms that come to a nice point. I have found the beams can be tighter that way as the thickness of the mirror doesnt come into play.

EDIT in this case I see your stacking so it wouldnt matter, but curious about the choice in other builds now i guess
