Update: OK so I had some time today and I tested the Red 5mw 635nm on a Professional Laser Meter and I got only 4mw for it. For...

Yea I know what you mean, I almost thought it was gone; Update while I can read all of the threads, it won't let me login & thus I can't post yet.....they must still not be finished with its still nice because I was looking for some old threads...
Re: How to Build Home Made Laser Power Output Mete
Cool, I'll then leave that up to you then; I'm extremely busy this week so I don't have anymore time to devoted to this project. However I will say the tests I conducted were done carefully and accurately with a $450.00 Beckman Bench DMM.
I...

OK so I got my unit and here is what I found, first off I'd like to start off by saying his Ad is *very* misleading; here is a paste/copy quote right from his Ad, Please notice the Color for that part of his message in his Ad on ebay, it is...
Re: How to Build Home Made Laser Power Output Mete
Let me clarify, I do expect it to be a lot more accurate than the led method, which I found to be a complete joke. But I don't think it will rival the coherent. I would expect it to be fairly accurate and the results to be repeatable. If it...
Re: How to Build Home Made Laser Power Output Mete
The unit is calibrated for 633nm and he provides a very simple chart for the correction factor, I don't see much of a big deal with that if it all works. OF-COURSE it's not going to rival a Coherent Lasercheck, I would not expect that of a...
Re: How to Build Home Made Laser Power Output Mete
Yea I tried the LED method & wasn't pleased, but your right it gives you atleast an idea. I'm going to use a ND8 filter with anything over 10mw that I have and see how it goes. I then will compare it against a Coherent Lasercheck starting with...
Re: How to Build Home Made Laser Power Output Mete
Interesting, because I was told you can push the sensor to 60mw and no more; but probably could use a filter for higher power measurements. I ordered my unit 4 days ago and should be here soon, we shall see. I have numerous 5mw red & greens to...
Re: How to Build Home Made Laser Power Output Mete
Check on fleebay, there is a guy that is already selling them from Canada. His only goes to 50mw, but you could put a density filter in front of the sensor just like everyone else selling meters below $500.00 does.
