I made this LPM but since I don't use it (I prefer my Laser Precision power meter) I might as wel sell it. It uses an Ophir OEM thermopile. I recoated the sensor disk because it had discolorations, it now looks and works fine. I've tested a similar recoated head with more than 10W with a fiber coupled 808nm diode bar and it worked just fine.
It's a very small unit, very portable and easy to work with. I'll be honest that the inside is quite cramped (I didn't plan ahead enough). It uses a single 9V battery, replacement requires some fiddling to get everything back in the unit. A DC-DC converter provides the negative voltage, this way only 1 battery is needed.
Dimensions:
readout: 84x54x44mm
Head:38x38x34mm
Measurement:
Resolution: 1mW
Range: 0-5.000W
Rise time: ~0.8 sec 0-95%
All that for 225 euro asking price (without shipping), feel free to make offers, but my guess this is a steal for an Ophir based LPM. The almost instant risetime, 5W measurement range and 1mW resolution make this a very nice LPM.
Let me know if you have any questions, if you want a video of it working or more detailed pics. PM's are welcome.
