Finally!!!!
My scientech 362 powermeter I was talking about arrived!!
It was in the best shape one could imagine.. not a single scratch!
I hooked it up right away and started measuring my lasers.. I couldn't resist sharing this on PL
First with my projector currently only containing a 150mw (as how it was sold to me) greeny:
After all optics (dichro, x/y) .. only 70mw!!
I removed the scanners.. then I measured 90mw after only the dichro.
Final stage:
the greeny without optics measured at 130mw.. well close to 150mw don't you think?
Now ofcourse I expect that this meter needs some calibration.. but i can at least determine some relatives..
30% loss on the dichro? Is that normal?
Then I measured my 635 red which was sold to me as a 300mw..
A whopping 60mw!!
Maybe it's calibration is way off.. but considering it was doing well with the greeny i think i got conned bigtime on this..
Too late to ask for a refund i guess..
Someone here who has experience with calibrating these babies? I read somewhere the 2 white connectors should be used to power up an internal resistor of 40 Ohm.. you should be able to measure the exact amount of mW's put in to the resistor..
is that correct?
