I bought the blue "gatling" style 405nm laser on ebay, and wanted to get safety goggles before using it. I am considering three pairs from survival lasers, but I am not sure which to get. Either the 190-540nm standards, the 190-540nm+900-1700nm, or the 190-540nm+800-2000nm. I know that most green ebay lasers emit plenty of unfiltered infrared, and I want to make sure I don't damage my eyes. Also, if the laser does emit IR, would it be 900-1700nm or 800-2000nm? It seems like a very slight difference, but there are two different goggles and the 800-2000nm ones are more expensive.
