    On quad multimodes, say 520 or 445, its also necessary 2mm efl on all 4 diodes for stacking beams and obtain better 'square' FF beam profile. With 2mm on Nichia 1w 520 for example, NF beam is 1,7x0,98mm on one diode. stacking 2 diodes is 3,4x0,98mm, so 3,4x 3,92 after expansion (x4) great for 4mm aperture scanners. With G2 lens, NF is 5mmx1mm, so stacking makes a 10x1mm beam, 10x4 after expansion .
    Isn't it?
