    Default NUBM08 new blue diode (455nm, 4.3W)?

    NUBM08 4.3W 455nm Laser Diode

    The new stock lens looks to be a shorter focal length lens.





    I will add more details as I get time to test them. The divergence from first glance seems the same as the NUBM44.

    The diode has a pretty hard knee at 5A. I think 4A will be the sweet spot for this diode. It is bluer than the NUBM44 but not nearly as blue as the NUBM07E. In the middle mabye a little closer to the NUBM44 but that bump in wavelength will give it a pretty serious bump in visibility.

    455nm pretty close to 457nm from argon

    We have the old colors back

    Is it usable for a projector though? If it's similar to NUBM44 I've read the beam is too fat and divergent.

    PS. @DTR: did you remove NUBM06 from your site?

    As I thought the divergence is an exact match with the NUBM44. Here are both with G-2 lenses.

    Guys, usable for projectors?

    @DTR: where did NUBM06 go?

    Yes, usable..I'm testing one these days, but the question is...which beam specs do you expect to achieve?

    What will be the beam dimension at 1 mrad divergence? would like to know what scanners could fit.

    You should expand in between 5,4-5,6mm to get 1mrad. Divergence is crazy, almost 16mrad with stock lens, so even worse than P73.
    At 5mm expansion I get about 1,4-1,5mrad...

    Any way to know exact stock lens FL? Based on diode specs/beam NF profile, it seems about 3mm FL, but I'm not sure

    Is P73 that bad? I thought the 5.6mm diode produced smaller beam than the 9mm green and blue diodes. Sorry off topic.
