In this case, a 20W LPM sensor...No sense in investing in CO2 if I can't measure it!

The "fins" are the heatsink from an AMD Avalon processor package I picked up for $3. I cut it down w/ a hacksaw and drilled it out to screw-mount the side pieces and will use ceramic thermal adhesive to stick the top piece down. It will then be mounted to the project box/PS for the unit to go with my DMM.

This is more than enough heatsinking that I can measure up to 20W lasers...if I work out a better PS system for it...something wall-plugged.

Woaah! That's a monster 20C Ophir now, I would point all my 445nm's just for shits n giggles!

Btw where are you going with this? 5 diode kit ? :eg:

Neat!

I'm still waiting on mariomaster to finish converting my analog 20W coherent meter to digital. Just be careful you don't scorch the coating off! :beer:

Now watch him buy a 40W CO2 and not be able to measure it.:D
Good job though SBA.

Going to have to use 4x 9V batteries to get 20W out of that! :p

Edit: I apologise for the late night miscalculation :tired:
Two 9V batteries in a 2S2P configuration would only give about 14-18V which is not enough for 20W.

Thanks, all. I am ultimately planning on using an 18VDC laptop PSU to power this setup. I just have to figure out the circuit. It will be complete with a high-current DPST switch and banana jacks to plug into a DMM and a USB connector for a future ARG board with data logging in it. In the meantime, I am going to enjoy this bulletproof DIY setup.

I still have another Ophir that I can build another heatsink for and package together for anyone who wants it!!
