A proper laser safety goggles test (your help needed)
I was ordering some diodes and housings from an eBay seller and noticed he was selling some quite cheap laser safety goggles as well. Since they were very cheap I decided why not get them and test just how usable and safe these cheap safety goggles really are, since I have a LaserBee AXA power meter now.
I don't want to provide the name of the seller because even if it turns out these goggles are useless he is a decent seller and I'm sure any other chinese seller who sells such goggles is pretty much selling the same thing anyway, so if the results are not positive it would be best to avoid them all.
But I am going to provide photos of the goggles and my readings.
To start I just want you guys and gals to suggest how to properly set up this experiment.
The power meter has a maximum power reading of 5 Watts for a 4mm beam profile, the reading increment is 1mW and 100% accurate reading takes 40 seconds of exposure.
There are 4 goggles, 2 $40 OD4 (red, green+blue) and 2 $10 OD5 (red, green+blue). The OD4 ones came in a case with "Eagle Pair" on them, the OD5 ones with "T-Rex" label.
I have 200mW DPSS 532 green module at my disposal, 300mW DPSS 638 red module, 1W 520nm green diode, 800mW 445nm blue DPSS, 3W 462nm diode and 500mW 638nm diode at my disposal I can use for testing.
