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

[Bbe]

At last I has cracked the mystery of quad mitsu setup (and who killed Kennedy)

Of these days I finished my first multimode red quad setup. 2100mW@800mA/each diode. Better than 4x4mm beam at the aperture. TEC cooled at the 15° celsius. High-performance driver inside.



Special thanks to Dave for his optics kit!

That was Morbid Morley.

what driver is that?

His he has them listed here somewhere.

Drop the blue "laser like" killer LED. My pet leave, blue LEDs that kill your night vision....

This is my dual driver with a onboard tec and dc-dc

My cat told me, it doesn't bother her. The main thing - the tail

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

nice! when do i get one?

If using cylinder lenses, I read that a few centimeters after the diode lens is best, so that path length might as well go through the cube. If one of the diodes gets a half-wave plate to rotate polarisation without rotating the beam profile, you only need one set of correction optics (cylinder lenses, or anamorphic prisms) after the cube. I doubt there's any significant gain is doing it differently, and you'll lose money trying.

ok,
thank you for the information,
