Another one 2W red module (4x 638nm mitsu)

[Bbe]

you put your correction optics after the cube?
correction before putting a cube, its quality is it better?

There is no theoretical difference if you can arrange the optics so the required distances between the elements.

nice! when do i get one?

You can kidnap it from me, when I sleep

i find your terms acceptable....

ha-ha, OK, let me know the day when you will come, I shall get drunk before it to have a good sleep

i find your terms acceptable....

btw, does anybody know any statistics on what happens when you overdrive your mitsu diode, say, at 50%? Are there any statistics of lifetime?

Some times I was asked to show the beam profile and to measure the divergence. I added the results below:

The beam at the aperture ~ 3.8mm (V) x 3.6mm (H)


@6m ~ 9mm (V) x 11mm (H)


If use a calculator, we get the next divergece: ~0.9mrad (V) x 1.2mrad (H)

Beam shot @6m

Nice job! Packing all that into such a small module isn't easy. How did you find the alignment process ?

Out of concern for the alignment process I used an extra bounce prior to stacking to make the process easier and also one before the cube, but took so much space compared to this.. Nice tight build!

Did you make that housing as well ? If so, any plans to sell those ? Or maybe housing + driver kits ?

that is really nice.. if you did some spatial filtering, you could clean up those wings.

are you going to sell these? i'm kind of in the mood for a lot of red.

any chance you will reviel what fl lens you used , and the mag of you cylinder lens set ??

It's very simple. First I modeled the beams stacking in a virtual space. Next I repeated it in hardware

Perhaps the next module will be even less

Yes, it's 100% my hardware, except for optics.

Did you make that housing as well ?

Maybe one fine day

If so, any plans to sell those ? Or maybe housing + driver kits ?

A little bit more and will be easier to build a 12x single-mode diodes module

How much are you in the mood to pay for it? Perhaps we will agree

Special thanks to Dave for his optics kit! #

Seconded. Although I think the clue might be in the first post. I decided to sample one of Dave's kits. I like to design my own stuff but there seems to be a wheel here too good to reinvent until I have tried it. And I don;t expect to beat it either. Perhaps shrink it a tad, if I'm lucky, but no more. Any detailed confirmation on lens specs is good though, I for one can't afford to spend lots of money on the wrong optics! Bbe, please let us know if you used something different to Dave's 'red kit' parts to get this performance because it is good, probably the best reported I've seen so far.

Edit: Looks like I got my answer. Posted while I was still writing mine..

DOH!! i should pay more attention my bad
