Hi All,
I recently salvaged the blu-ray laser diode from a Sony Blu-Ray player and have built a driver circuit and purchased a blank Aixiz Laser Housing. The driver seems to properly power the diode so I placed the diode and driver into the housing. However, when the laser is turned on I am unable to focus it into a beam. I am able to focus the light to a point on something a few inches away, although once the light hits something further away, 10ft or so, it has expanded to a dot about a inch in diameter.
To me this is indicating that the beam is not collimating. Is there something that I could be missing or could there be an issue with the lens/diode.
Any help or hints would be greatly appreciated.
Thanks
