M140 Correction Results - pics

[jjspike]

Hey all,

I wanted to post these pics and receive some feedback. I used a set of 6X cylindrical lenses to correct my M140s. It took a fair bit of futzing-around with the lenses to get things right (at least what I thought was right). Please let me know if I'm on the right track:


Near field @ 28cm after clyindrical lens - Inner dot = 2.65mm, End-to-end (wings)= 7.03mm (not sure if this will be an issue)
The wings are not nearly as bright as the dot in the center however the camera does not show this properly.




Far field @ 9.2M - 6.7mm Width, 5.8mm Height



Feedback would be appreciated.


Thank you

Nice work! I would love to see the setup of 6X cyl lens that seems rather intense aha! However, looks like it paid off.

Thanks For sharing Your results!
I'm going to do a similar thing but with an ebay lens from seller Techhood with the m462 nm and oclaro 700 mW red diodes + 3 element glass lens collimators. I will put more information ,losses on the lens kit ;NF-FF beam patterns scanned beams ;divergence datas and more.

Best Regards from Hungary

Unfortunately, I tore the setup apart after I took the pictures as it was only for experimentation. I will do it all over again when I receive the rest of my parts. I did keep measurements so it should be simple.

I will test green tonight and post the results.

Does the near field beam look correct and will it work given the "wings"?


Thanks

It appears that all you need is a little spacial filtering to remove the "wings". You've definitely nailed the collimation though. Those beam spot measurements are very good.
