    I do have a couple different variations telescope glass to play with.

    if you use the optima lenses you can expect a beam of 2x3.5mm from each diode @ 0.5 mrad with less than 1% loses.

    You can combine 6 diodes like ::: and get a beam of approx 6x6.5m.

    then all you have to do is choose the appropriate ratio telescope. if you choose 3:1 you can have an exact match for most dpss green beams (approx 2mm diameter and 1.5mrad divergence)

    Why would you get broke?
    six Optima lenses are somewhere in the 120 a 180 dollar region...
    Loc diodes are not to expensive....
    Are those telescope optics expensive?

    You talking $30 per lens instead of $5 or less for the aixiz or olike lens so on a 12 diode build you would be an extra $300 or more.

    The current project involves testing with multiple lens combinations.

    my current stack is

    ...
    ...

    But will be testing even more stuff soon.

    telescopes I think are $50~$60 for a pair then whatever mount you need.

    Don't forget that with an aixiz lens you have a 25-30% loss v. <3-4% loss on the Optima, which means you need about 25% more hardware to get the same results in power with the aixiz lens.
    Not to mention the subject of beam quality and also not mentioning that 3-4 Optima collimated beams will fit into the area of 1 aixiz collimated beam.

    Just my accumulated experience after having worked with both lens types (amongst others).

    Cheers!

    Thats exactlly what i thought...
    Using inferiour optics would cost you more in the end.

    I could justify the use of a cheap Loc diode over a more expensice opnext 637 diode....
    But than again.... you need less power.. less hassle with isolating the diodes from ground.
    I think it's all about costs vs performance... most bang for the buck.

    Did you do tests with telescopes?

    I think once you see a beam with the Aixiz after telescope you will change your mind on using this lens or similar. Its possible to get a decent beam but not worth the time and impossible sometimes. And its impossible to get 12 different beams to be right; you may get a few of them to have decent divergence after the telescope but not all of them.

    When starting this time consuming build you have to make sure you avoid things that can waste endless hours of your time. like lenses in sloppy threaded mounts (like aixiz), just my 2 cents

    Yep I figured that but was gonna still plan on testing wit ha block of 6, just to show and gain more info. i still have some not much but a little hair to pull out
