Another one RB 445/637nm module build (with single-mode red)

Previously

Hi guys,
This time I decided to make the module with more better divergence specs. As usual, I will use my own hardware, drivers etc

To start a few renderings:



Eight single-mode diodes stacked into a one array, two NDB7875 combined using polarization method.



This is not the final design, afterward I had to use a phase rotators, instead a wave plates ((



A bit later I'll post the actual hardware photos and assembling process...

Awesome! Looking forward to seeing the end result

Nice one.... interesting to see what beamspec you end up with !
Hope U post pics when it's finally built !
Cheers

Some hardware porn ))

For red array I'll use one of my diode housings

Luverly ....

thumbs up .

Presses like. Very neat and smart looking housing plus diode blocks.

Where to buy the best driver for your module? - Make it yourself!

My solution (not only for this project) -
3 channel diode driver (highside design) + 1 channel TEC driver (highside design)

Specs: 3A/diode channel, 250ns rise time (500khz bandwidth), overmodulation (5.2v+) clipping, low thermal drift, SBS, etc
8A/TEC channel, 60Khz PWM with optimized PID table

I hope your selling them!

I definitely want to buy few pcs!

Looks fantastic Vladimir - the wait has paid off I can proudly say that these beauties are going to sitting in my projectors soon!
