    Doohickey for measuring Laser Power

    I have done some searching without much success. Russ Stadler uses a Doohickey to measure Laser Power. I read someplace that he sells these but I have not been able to find anything. Any feedback on where to find them and there use is apriciated. Thanks, Dan

    You can email him for them. You can also rent them from Light Objects I believe at lightobject.com. They may also sell them.
    I saw them for sale on Amazon but they have been out of stock for about a year. I havent hunted for one beyond that though. They ran about $100 for a 100 Watt capacity unit I believe.
    Or if you are adventurous you could make your own by looking at Russ Sadlers videos. Particularly https://www.youtube.com/watch?v=lO9rWlobLZU
    900x600 80watt EFR Tube laser from Liaocheng Ray Fine Tech LTD. Also a 900x600 2.5kw spindle CNC from Ray Fine. And my main tool, a well used and loved Jet 1642 Woodlathe with an outboard toolrest that helps me work from 36 inch diameters down to reallllllly tiny stuff.

    Daniel, you can contact Russ through his youtube channel to order the doohickey. He is very quick to reply and a hell of guy. Here is the link to his channel:

    And the reason you can't find them anywhere else is he has these made for himself and is the only source for purchase at the moment.

    Daniel, one other thing. The cost for the doohickey from Russ is £30.

    I got one of these guys:

    which seems to work pretty well. It's more expensive than £30 though!

    Hi Brian, please message me Russ's email. We're there any issues with shipping or importing to Canada?
    Thanks again

    Russ ships into the mail stream very fast and I appreciated being able to support him after all he has done for the Ruida controller community.

    I would go on ebay to look for one of the K coupler (or whatever they are called) digital thermometer readout units. I found one that shipped from the US for $15 and it arrived faster than China. When buying, make sure your purchase includes the two sets of wires.
