Finally my ophir head arrived and i did a short test of my greenie with the Lasever module. I did the test with the 2x9V battery setup and a multimeter. Excitingly the readings were almost all the time over 1W and it maxed shortly out at 1,266V wich would be 1266mw :eek: edit: batteries were pretty low, see new results!
Sadly i have to trust the factory calibration so far. And i can´t do a datalogging... but i think it would be worth buying someting ;)
Now charging batteries and then i´ll do some more testing.
Since i do not have an internal temperature control, i am not going to do test exceeding 1-2 min runs.

Video edit:
1,6 watts!!!

i just saw that i did it like that. its connected as in your pic (brown cable connected to the cable as you showed it. I did read the thread to the end where the correct connection is shown ;)
 
damn... its getting better and better... battery almost fully charged, over 1,2w for half a minute. peak was at around 1360mw :wave:

video will follow with run over 1,4w...

it´s pretty unstable... that gets better after warm-up time. but some of that jumping remains.

How much of this power output do you reckon is IR? I haven't gotten to play with one of these modules yet.
 
don´t think its very much, since it was shipped with an anti IR coated glass. how can i test it the best? (without destroying my safty glasses)

edit: ok, couldn´t resist. with my safetygoogles in front it produces 5mw. since they do not filter IR it looks good to me. now i got two little burning marks on the glasses (just put them in there for 2-3 seconds) :/

lol...not the approach I would have taken, but ok. I might have tried a glass IR filter, covering the wavelength in question.

I don't know how real-world your test may have been. They won't let me crunch variables all day at work..

i don´t know eighter, but the test should be fine. ARG Laser told me these ophirs are pretty good factory calibrated. the voltmeter should work (i use it almost every day and i had it compared against others), i had it set to 2V wich is in the range and should give me a precise reading. the 9V batteries are of the shelf and the wiring is right. i know, it looks very messy, i was in a hurry with testing it the first time ;)
