    Ⅳ. Conclusion
    1. Based on above test result, we found the beam-shaping of 462nm phi5.6mm is easier, and the beam mode is
    better than 462nm phi9mm. For 462nm phi5.6mm diode, we use a pair of prism, but 462nm phi9mm need
    two pairs of prisms, so the near beam of 462nm phi9mm is bigger.
    2. In the case of same current, the power of 462nm phi5.6mm is higher, so the heat is less.
    3. The 462nm phi5.6mm near beam is smaller, so it’s easier to make higher power laser combine with many
    diodes.
    4. Most important, the price of 462nmm 5.6mm is more suitable.

    Thanks for the test, however... could you share please?
    -Diodes reference/brand/price
    -collimators used
    Thanks

    That's a damn nice beam! What are the final specs for the 5.6 module. Divergence wise? 2watts at 1mrad? 3mm at aperture. Is this single mode? I like the result I see.

    I see they are the same in the far field.
