    If you need to ask the question 'whats so good about a laser' - you won't understand the answer.

    I've already placed my order via mccarrot, but I was wondering what the divergence parallel/perpendicular of these is?

    If the buy is still open, I will take 8 of the LPC815.

    Regards, Dan.

    I mean the divergence of just the red diodes
    Without lens. As one would specify in a data sheet.
    If that's not available I would understand ...

    Those red diodes are all singlemode diodes, with good optics a divergence lower than 1mRad and a beam smaller than 2,2mm should be possible.

    My current 16x diodes do 0,8mRad with 1,2x2,2mm beam with my current optics. (but they are not cheap )

    It should be possible to get them at 0,6mRad but my room is too small .

    Kvant got a nice solution for this, a hallway of about 30 meters with a webcam at the end to film the beamsize. I have the the webcam, only my house is only 10 meters long .
    Not sure if bounce mirrors would effect the beamsize else I could bounce the beam a couple of times up and down my room the get the biggest distance.
