    Default P73 scanned.

    Skip ahead to about 1:30 in the video. I don't think anyone has posted it scanned yet, figure some maybe interested.

    Nice! Still waiting on parts before I can start on mine.

    Is the red loss off of 7x12mm mirrors?

    OK. Good!

    Now, the divergence does seem high. Is this due to saturation of the camera or are the far field spots a little fat? If they are fat are the diodes well aligned or is each diode producing a slightly defocused beam?

    One way to tame the red is to adjust the combined pattern prior to the scanner to the right aspect ratio. Assuming a 7mm x 11mm mirror, a square pattern should work THEN use a couple of lenses to telescope the square down just enough to prevent spill off the scanner. You will have to readjust the individual diodes' focus and the co-alignment just a frog's hair because you have passed the beam through some refractive optics.
