Re: Class 1 lasers
 

Note that there is a distinction between "Class I" and "Class 1". (The rules appear to call for the former, which was the designation used in previous versions of ANSI Z136.1 and IEC 60825.)

Also, the classification is valid for the entire assembled device, not the laser emitter itself (e.g. the laser diode). If you disassemble a device, its rating is no longer applicable.
