    Default For Sale: 2X Beam Expanders/ Telescope collimator for 445nm

    RE: pencil lead thin 445nm beam-no prisms no cylinderical lens, etc....

    I have seen postings in threads for a $50 unit. I have had these units in stock, and offered for sale for some of our red modules. They are just $30. Save $20 and buy them from a member!
    See link here:

    Default yeah

    yeah might start as a pencil beam but rapidly turn into a 6+mrad divergence
    no thanks

    This is only in response to some members working with these on 445 diodes.

    The resulting beam is discussed as pencil.

    Please keep off thread.

    I have no proof. I am merely listing an item for sale and saving someone $20 , if they so choose.

    maybe follow the thread with the title, as see after my "RE:" You can see their results there. Do I say this is the best solution to divergence?
    I am I not on the Lava cylinder list?

    Should I add a comment to not flame me because I did not prove something I never even stated?
    WOW, this may be a worse forum than LPF!

    Difference between LPF and PL is most PL people do have brains, so you can't sell them stories.

    When you decrease the beam size with a 2x telescope you end up with a higher divergence. When you increase the beam size you will end up with a low divergent fat beam.

    This setup could be used to decrease the beam diameter of a multidiode setup

    Don't know about that, I think the stories just have to be a shit load more complicated!

    I want to hear MORE stories here !

    Cheers
