    Default Open Source Laser Power Meter

    ARGMeter the Open Source Laser Power Meter

    ARGMeter is an open source laser power meter platform for the Arduino. The goal of this project is to give hobbyists access to a DIY LPM design for only the cost of hardware that they can expand and modify to suit their needs. This project has been through many prototypes and many designs, and is finally ready for release.
    Rather than clutter up a thread will all the details I put everything on a website for anyone to use. https://sites.google.com/site/arglaserpowermeter/home
    The project is continually under design and additions are made daily, if you see a bug or mistake please PM me or post here so that I may change it.

    This is very interesting. Might have to build me one of these.

    Default had to develop my own, if there is any interest i might go open source as well

    Hello, after much fidling with arduino, i managed to build my own laser power meter, it works based on calorimetry fundamentals and seems stable enough to read my 15 to 150watt Co2 lasers, anyone interested ?
    cheers

    Just a few basic questions.....

    What is the lowest power it can measure accurately ?
    What is the reading resolution and LPM accuracy % ?
    What is the current draw ?
    What is the sensing element and coating to get to a
    150 watt rating ??

    so far i was able to measure 10 watt laser acurately +- 5%
    and 15 to 100watt + - 2%
    resolution is .01 watt
    sensing element is anodized aluminum and carbon black coating
    convection cooled, might go higher power with forced air cooling
    but my most powerfull laser is 150 watt

    Default confused

    150w ??
    First what is w?
    do you mean 150mW??
    also this thread is 5years old.. so ...a necro .
    BUT nice that you are working on new LPMs ..

    just try to use these=(Mw=W w, MW & mW ) correctly..

    just did some research but

    w or W are still watts

    Mw or MW = Mega Watts
    mw or mW = Milliwatts

    so i did write as i meant to 150w (yes one hunded and fifty watts)

    about the thread being old, should the thread be duplicated just for being old ?, i did read the rules, and say try not to duplicate treads, if im wrong shouldnt this thread be closed ???

    an yes, im working on this power meter and would love to have some feedback on features that might enhance it functions, meanwhile here is a vide of a laser tube test, the tube was measured 24hr earlier and marked, then the test was repeated to verify its power level, so you can see the accuracy of the meter.
