It not hard to do, it's easy with pen pointers and only takes 20-30 seconds time or so each one (of course high end portable lasers do take time).
It's also the only way to show the true output.
If John's a drop shipper, then a meter will be of little use to him unless it's just to verify low output on returned lasers.
A sample of 5, 10 or even 15 units will be of little value statistically unless the reading he gets are all within small range, even then with so many variables like I mentioned in my post above, it would only apply for perhaps that days run of laser on that particular assy. line and assembler.
Using a meter to just sample a small lot every once in awhile will be little more than useless. I've been in the business for almost 6 years now and I'm speaking from experience here.
He doesn't need to put up a webpage listing each individual laser and it's output. All that needs to be done is that each is tested and the power level recorded and included with the laser, as long as a 50mw laser outputs 50mw or more, the buyer won't care and they will know exactly what the output power is.
I'll tell you one thing, it takes alot less time to just test them beforehand than all of the paperwork, time and money to arrange a product return, then test that returned laser and ship a new one that has been tested.
Best just to do it as early in the enitre process as possible or it costs a bundle in time, money and reputation.
Any average power data is infinity more valuable than no power data...statistically speaking
The testing of each laser just will not happen. If turn out wrong ill be the first to put my foot in my mouth.
