Sold: Bluefan 5W Ophir OEM based LPM

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.

That would be 225 Euro = $299.14 Cnd...
Does your LPM have any type of zeroing control
or do you have to wait until the head reaches
equilibrium...???
Does the Head cable disconnect from the Display
housing ??

BTW nice assembly...

Re: FS: Bluefan 5W Ophir OEM based LPM

Nice looking meter, looks very clean.

Re: FS: Bluefan 5W Ophir OEM based LPM

The ophir head itself has a zero control, once it's set it hardly drifts anyway. The cable is fixed to the readout and can be plugged out of the ophir head. The display has green leds, I'll get some pictures of it when on and with a laser on it. I'm currently at my parents so it'll probably be 2 days before the extra pics.

Re: FS: Bluefan 5W Ophir OEM based LPM

I waited for such cheap LPM.
Is not there the test video?

Re: FS: Bluefan 5W Ophir OEM based LPM

I'll probably post a video next tuesday, that's when I'm back at my place again.
