    Nice looking unit

    What are the dimensions of the laser module?

    Default Technical question

    Ok this one says 20hz modulation and sorry I'm still new but aren't we mostly using 10 Hz?
    Wiki:The first visible wavelength laser diode was demonstrated by Nick Holonyak, Jr. in 1962.

    Hi jooopy, I think you should multiply by a thousand here! KHz = Killer Hz LOL !

    Modulating between 10hz and 20hz the only thing you are likely to provoke is epilepsy among the small percentage of the population who suffer from this problem.
    However 10hz and lower is often used to flash freeze the punters dancing in discos etc.

    As far as modulation is concerned, (both TTL and Analogue) the faster the better!

    If you want colourful high frequency stripes in your ceiling scans this is essential.

    It sounds to me like you are somewhat limited by your controller/software or your scanners. Ideally you should be able to make every point scanned a different colour and on long scanner throws it's better if you can do it even faster as long as you have an analogue controller capable of supplying the frequency required and you can phase lock/shift it to the scanner frequency. It's a pig to do on a computer but a breeze with an analogue synthesizer and quite beautiful in the air.

    Most decent scanners will go up to 1k which means that you only get twenty stripes at 20k mod frequency.

    This 20k analogue mod speed is an interesting improvement!

    Good for you Shawn
    (ultralaser improvement duly, noted .......I will advise my Spanish clients accordingly).

    Best of luck with future sales.

    Cheers

    Default Gracias Catalango

    You are so right on the killer hurtZ. I got the FB3 dt40 wide combo and building the rest starting with a really nice 750mw 445nm. I believe the blue is modulated at 10khz as it uses drlava's new flexmod. Not sure if that is adjustable to match Shawns green here or if I even would want to match it. Like I said I'm new here. Nice laser Shawn.-jimmy

    Very good explaination on mod frequency !
    and thank you for your wishes !

    I am fairly certain the flewmod modulates WAY faster than 10khz; probably closer to 100k for both the new one and old one. I could be wrong; Andrew?

    I seem to remember the good doctor saying that the FlemodP3 has a 500khz bandwidth!

    Although I suspect he is using component specs rather than testing to support this statement.


    I could be wrong here
    but either way .....


    That is what I call FAST !

    Not that you'd ever need modulation speeds that fast for scanner use. Laser video projection maybe.
